Centrix, Equifax, and illion: What NZ's Credit Reporting Agencies Actually Check for Landlords

Three companies run credit bureaus in New Zealand: Centrix, Equifax, and illion (which trades its tenancy product as "Experian Tenancy"). Each one sells a landlord-facing tenant check. If you are comparing them, or wondering what a "tenancy credit check" from any of them actually covers, here is what each product page says, and the same question applied to all three: what are they good at, and what can none of them tell you no matter which one you pick.

The three agencies

Centrix

Centrix's landlord page is built around its Tenancy Check product: a standard consumer credit report (defaults, judgments, insolvencies, credit enquiries) plus a search of Tenancy Tribunal files. Centrix is New Zealand's largest consumer credit bureau by coverage, reporting comprehensive credit information on the large majority of credit-active New Zealanders. Unlike the other two bureaus below, Centrix was not a rebrand of an older company - it was set up as an independent competitor around 2010 by a former Baycorp managing director, and has traded under the Centrix name throughout. What their Tribunal search can and cannot find is governed entirely by New Zealand law, not by Centrix's product design: most tenancy disputes settle through private mediation and never generate a Tribunal record, and since February 2021 a wholly or substantially successful party can have their name automatically suppressed from a published order. See our full explainer on what a tenant credit check actually shows for the detail - the short version is that a Tribunal search is real, but it structurally cannot return a suppressed case or a mediated dispute, regardless of which bureau is doing the searching.

Equifax

Equifax New Zealand runs Comprehensive Credit Reporting for subscriber businesses. If the name feels less familiar than the other two, that is because it is the newest label on a much older business: Baycorp Advantage became Veda Advantage in 2006, Veda was acquired by Equifax Inc. in 2016, and the New Zealand operation was rebranded Equifax in March 2017. Landlords who dealt with "Veda" or "Baycorp Advantage" years ago are looking at the same underlying bureau today. Equifax's own Subscriber FAQ spells out exactly when a tenant's unpaid rent can reach a credit file, and it is worth quoting directly rather than summarising, because the bar is higher than most landlords assume: "You can do this provided you have a tenancy debt, you must have a sealed mediation order or a tenancy tribunal order before you are allowed to list the debt as a default against that individual's consumer credit file. You must have the supporting documentation to do this." A landlord also needs a Full Subscriber Account to list anything at all, and the default can only cover unpaid rent itself, not property damage or other non-credit matters. See the dedicated section below on why very few unpaid-rent situations actually clear this bar.

illion (Experian Tenancy)

illion Tenancy, trading as "Experian Tenancy," is the newest name for what was Dun & Bradstreet (New Zealand) Ltd until the company rebranded to illion in June 2018. It markets the broadest product of the three: up to seven years of tenancy history, tenant ratings, 14-day notices, Tenancy Tribunal orders, and what illion calls a "Tenancy Risk Score" blending credit bureau data with tenancy-specific data. Their own marketing also references drug-use warnings as part of that tenancy history. It is worth being precise about what that kind of entry actually is: a credit bureau's core strength is verified financial-account data reported by regulated credit providers, not a claim a previous landlord typed into a form. Where a tenancy product layers in landlord-submitted ratings or notes, that layer carries the same reliability caveats as any other unverified reference, not the reliability of a court judgment or a bank-reported default - worth knowing which kind of entry you are looking at before you weight it the same way.

What all three are good at

Since 2012, New Zealand has run Comprehensive Credit Reporting (CCR) under the Credit Reporting Privacy Code. Regulated credit providers - banks, finance companies, power companies, and telcos - can report up to 24 months of repayment history, including whether an account was paid on time. That means a person's power bill and phone bill payment habits do show up, and consistently paying those on time is a real, verifiable signal about financial discipline. All three bureaus draw on the same underlying regime, so this strength is not specific to any one of them.

What none of them can actually tell you

Rent itself is not a reportable credit account. The categories that feed Comprehensive Credit Reporting - home loans, personal loans, credit cards, utilities, telecommunications - do not include residential tenancies, because a landlord is not a registered credit provider under the Code the way a bank or power company is. A tenant's rent-paying history, on time or late, does not flow into any of the three bureaus' files the way a power bill does. The only path from unpaid rent to a visible credit file entry is the one Equifax states directly: a sealed mediation or Tribunal order for the debt, formally listed as a default afterward. Short of that, a landlord checking any of the three bureaus is not seeing rent history at all, clean or otherwise.

None of them verify employment or income. That information comes from whatever the landlord collects directly - a payslip, an employer letter - and none of the three bureaus cross-check it as part of a standard report.

None of them measure whether someone is actually likely to pay rent. A credit file describes formal financial history: debts, judgments, insolvencies, and now utility payment habits. It does not describe intent, and it does not describe the specific behaviour a landlord actually cares about - reliability as a tenant, communication, how someone treats a property. Where a product bundles in something closer to that (illion's tenant ratings, for instance), it is drawing on landlord-submitted input, not verified financial data, and is worth weighing accordingly.

A low score can be unrelated to how someone actually pays their bills, let alone their rent. Anyone who agreed to be a guarantor for a family member's loan, a sibling's business loan or a friend's car finance, carries that risk on their own credit file. If the borrower defaults, a guarantor default gets listed against the guarantor under the same rules that apply to the actual debtor, even though the guarantor never missed a payment of their own. A large one-off bill from a medical emergency or a car repair that went onto a personal loan during a hard year can have the same effect, and it stays on file for five years under the Credit Reporting Privacy Code regardless of what has happened since. A young applicant or someone new to New Zealand can also score low for having too little credit history to measure, not for having a bad one. None of these describe a person's reliability as a tenant. A low score is a reason to ask more questions, not a reason to decline on its own.

All three of these limits are structural, not a gap any one bureau will close by adding a feature. They follow from what a credit bureau actually is: a register of formal financial-account history, not a tenancy record.

Most unpaid rent never reaches any of them

Getting a sealed order is only half the requirement. The Credit Reporting Privacy Code 2020 itself defines what actually counts as a reportable "debtor credit default," and the definition sets a high bar. An overdue payment only qualifies once the individual is at least 30 days overdue, the credit provider has notified them and requested payment, and, critically, the credit provider has taken further steps beyond that notice to actually try to recover the money. The provider also has to be legally free to sue for it, and the amount has to be at least $125. A single unanswered notice is not enough on its own; the law requires an active attempt at recovery before a default becomes reportable at all. See the Credit Reporting Privacy Code for the full definitions.

For a landlord, clearing that bar means going through mediation or the Tenancy Tribunal first, since that is what produces the sealed order Equifax's own rule requires, and Centrix's and illion's Tribunal-search products depend on a Tribunal record existing in the first place. That process has real cost in time, even where the application fee itself is small. Tenancy Services data obtained under the Official Information Act, reported by RNZ in 2026, shows rent arrears cases made up over 60 percent of Tenancy Tribunal applications in the previous year, the average wait for a first hearing was 48 days, and arrears-specific cases could take up to three months to be heard. One Waikato property manager quoted in that reporting described the debt piling up during the wait as "devastating for landlords as well as tenants."

There is also a simpler reason many landlords never start that process at all: a tenant who has stopped paying rent or leaves owing money is very often the same tenant who has nothing left to recover it from, and pursuing a debt through mediation, a Tribunal hearing, and then debt collection against someone with no income or assets rarely recovers the money even with a sealed order in hand. The section below on landlord insurance covers what landlords actually do about that instead.

Put those two things together and the practical picture is different from what most landlords assume. A tenant who pays consistently late, who falls behind and then catches up, or who leaves partway through a tenancy owing money the landlord decides is not worth months of mediation and a Tribunal hearing to chase, especially once the tenant has already gone and has little to recover from, generates no sealed order, no reportable default, and therefore no trace at Centrix, Equifax, or illion. None of that is a flaw in any one bureau's process. It follows directly from what the law requires before a rent debt is allowed to become a credit file entry at all, and from the ordinary cost-benefit decision a landlord makes when the debt is smaller than the effort of formally pursuing it. A completely clean credit check is consistent with a tenant who has never missed a payment, and it is equally consistent with a tenant whose landlord decided the debt was not worth chasing.

Insurance, not a credit check, is what actually protects you

Everything above points to the same practical conclusion. A credit check cannot show most of what actually goes wrong in a tenancy, and even where a landlord does everything right, mediation, then a Tribunal hearing, then a sealed order, the tenant is very often the same person who has nothing left to pay the debt from. Pursuing the full legal process against someone with no income or assets rarely recovers the money, sealed order or not. This is a large part of why landlord insurance exists as a separate product from a standard home policy: cover for malicious or intentional tenant damage and loss of rent is built specifically around the case where a tenant cannot pay for what they owe, not the case where they refuse to. See our full guide to landlord insurance for what a policy should actually include.

A landlord whose tenant causes tens of thousands of dollars of damage, or stops paying rent for months, is very often better off filing an insurance claim than spending months pursuing a Tribunal order against someone who cannot pay it either way. None of that path touches a credit file at all: an insurance claim is a private matter between the landlord and their insurer, not something Centrix, Equifax, or illion ever sees. And even where a landlord does go the full distance, mediation, then Tribunal, then a sealed order, the tenant can still apply for the name suppression covered in our companion article on what a tenant credit check actually shows, so months spent on the formal path can still fail to produce a searchable credit-file record at the end of it. Insurance does not depend on any of that working. It pays out on the landlord's own policy and evidence, not on whether a tenant is ever traceable, solvent, or willing to engage with a legal process at all.

That does not make insurance a free pass either. The Insurance Council of New Zealand's own guidance to landlords lists ongoing duties that keep a policy valid: taking care in selecting tenants, with satisfactory references given as the example, collecting and registering a bond, monitoring rent in arrears, and inspecting the property. Many policies go further and specify inspections on a fixed schedule, commonly every three to six months, and can decline or reduce a claim if a landlord cannot produce inspection records showing damage was not left to develop unaddressed. In other words, an insurer that pays out on tenant damage or unpaid rent is checking, after the fact, that the landlord actually did the screening and the ongoing management a landlord is supposed to do, not underwriting a landlord who skipped it. Insurance is a backstop for a genuine loss you could not have reasonably prevented, not a substitute for having done the work in the first place.

A $15 report is not the same as due diligence

A cheap, fast check is an easy path to take, and it is tempting to treat it as the whole screening process, especially when it is the only step that costs money and produces a document. That is the trap: a landlord who pays for one check, reads a clean-looking report, and stops there can end up more confident than the check actually justifies, for every reason set out above. An experienced property manager treats a credit check as one item on a longer list, not the list itself. Alongside it: an employer reference to confirm the job and income an applicant claims are real, a reference from a previous landlord (ideally the one before the most recent tenancy, who has no reason to give a flattering account just to move someone on), a character reference from someone outside the tenancy relationship, and, in common practice, the applicant's last three months of bank statements. See our guide on checking tenant references for who to ask and what to ask them.

A single payslip can be altered. Three months of transactions are harder to fabricate, and answer a different question than income alone: what regular commitments does this person already have, and does their income cover them with room left over. It is the same logic a bank applies to a mortgage applicant it has no existing relationship with: rather than take one payslip on its own, the bank asks for months of statements from wherever the applicant actually banks, to see disposable income and existing repayments, not just gross pay. The point of reading a tenant's statements is narrower than it sounds. It is not about how someone spends their money day to day. It is two things: whether rent has actually been going out on a regular pattern, and whether salary or a benefit has been coming in on a pattern that covers it.

Worth knowing before insisting on this: the Privacy Commissioner's own published guidance for landlords goes the other way. It recommends collecting only one piece of income evidence, a payslip, an employer letter, or evidence of rental payments in a previous tenancy, and states plainly that landlords should not ask for detailed bank statements. That guidance is not itself legislation; it is the regulator's own interpretation of the Privacy Act's existing collection principles, not a separate law with its own penalties. Bank statements remain common practice among experienced landlords and property managers regardless, but it is worth knowing this particular part of that practice sits against the regulator's stated position, not alongside it.

Some screening services go a step further and try to monitor an applicant's social media accounts. That is not a shortcut to a better answer, it is a legal problem. The Privacy Commissioner's own guidance for landlords is explicit that social media URLs should not be requested when selecting tenants, and that seeking access to a profile restricted to friends and family is "unreasonably intrusive on individuals' personal affairs" under Information Privacy Principle 4. Set the legal exposure aside and the practical case is no better: scrolling an applicant's social media does not say anything more reliable about whether they pay rent on time than a conversation with their last landlord does. It adds risk without adding a real signal.

What actually covers the gap

The part a credit bureau cannot see - whether someone pays rent reliably, communicates, and looks after a property - is exactly what a previous landlord already knows. RentManager's own reference-check tool sends a previous landlord or employer a secure link by email, they answer a short structured form on their own time, and the written answers land on the applicant's record with a timestamp, turned into a recorded outcome by a guided wizard rather than left as an unreviewed email.

Quick answers

What are the three credit reporting agencies in New Zealand?

Centrix, Equifax, and illion, which trades its tenancy product as "Experian Tenancy." All three sell a landlord-facing tenant check.

Does a Centrix, Equifax, or illion tenancy check show unpaid rent?

Only if the debt reached a sealed mediation order or Tenancy Tribunal order and was formally listed as a default afterward. Ordinary late or unpaid rent that never reached that point does not appear on any of the three.

Can a low credit score have nothing to do with someone's tenancy behaviour?

Yes. A guarantor default on someone else's loan, a one-off medical or car-repair bill, or having too little credit history to measure can all produce a low score without describing how someone actually pays rent.

Does landlord insurance depend on a clean credit check?

No, but it does depend on the landlord having taken reasonable care in selecting and managing the tenant, including references and regular property inspections. Insurers can decline or reduce a claim if that evidence is missing.

Is it legal to check a tenant's social media before renting to them?

The Privacy Commissioner's guidance for landlords says not to ask for social media URLs, and that accessing a profile restricted to friends and family is unreasonably intrusive under the Privacy Act.
