Tenancy Tribunal Evidence Checklist (NZ): What to Gather Before You File

Most landlords lose at the Tenancy Tribunal not because they were in the wrong, but because they could not prove they were in the right. The adjudicator decides on the evidence in front of them, not on how strongly you feel about it. A tidy, dated record beats a long, angry story every time.

I have been to the Tribunal twice. Both times self-represented, both times I won, and the reason I won was not that my cases were exceptional. It was that I turned up prepared: a spreadsheet of every rent period and payment, a clear understanding of what the Tribunal actually considers reasonable, and a one-line justification ready for each amount I was claiming. That preparation is what gave me credibility in the room. The adjudicator could see I was not guessing.

This is the checklist I wish someone had handed me before the first hearing. Build the habit from day one of a tenancy and the evidence is already there if you ever need it. Leave it until you are angry and filing, and you will be reconstructing it from memory, which is exactly when it falls apart.

The short version

Before you file, you want these in order. The first one is not optional; the rest depend on what your dispute is about:

1. The signed tenancy agreement. The foundation document, no matter what the dispute is.
2. A rent ledger showing every period, every payment, and the exact shortfall - if rent is in dispute.
3. Inspection reports with dated photos, from the start of the tenancy onward.
4. A move-in and move-out condition comparison, ideally the same camera angles.
5. Every written message with the tenant, unedited.
6. Quotes and invoices for any repair, cleaning, or replacement you are claiming.
7. The notices you served, with proof of when and how you sent them.

The rest of this article is what each one looks like in practice, and why it matters.

1. The signed tenancy agreement (the foundation)

This is the document everything else hangs off, and it is the first thing the adjudicator wants to establish: who the parties are, what the agreed rent is, the term (fixed or periodic), and what each side signed up to. Without it, the Tribunal cannot anchor anything else you bring. A ledger showing a shortfall means nothing until the agreement proves what the rent was supposed to be; a damage claim depends on what the agreement said about the tenant's obligations.

Bring the signed copy, with any variations (rent increase notices, agreed changes, pet or other addenda) attached. If the tenancy was never put in writing, that itself is a problem worth raising, but you can still proceed on the address, the parties, and the bond record.

2. The rent ledger (when rent is in dispute)

If your claim involves money, this is the document the adjudicator reaches for first - but it only matters when rent is actually contested. If your dispute is about damage, entry, or a notice and the rent was always paid in full, you do not need a ledger. When rent is at issue, it has to show three things: what rent was due each period, what was actually paid, and what is outstanding. A bank statement is not a ledger. It shows money arriving, but it does not show what the rent was supposed to be, so the adjudicator cannot tell a short payment from a full one without doing your arithmetic for you. They will not do it.

When I went in, I had a spreadsheet with one row per week: rent due, rent received, running balance. The adjudicator could read the arrears off it in seconds and the number was not in dispute. That is the difference between "the tenant owes me roughly two months" and "the tenant owes $1,840.00 across these eleven periods, here is the row for each one".

What the adjudicator wants to see:

• Every rent period from the start of the tenancy, not just the ones in arrears.
• The expected rent for each period, matching the rent schedule in the agreement.
• Each payment matched to a period, including partial payments.
• A clear closing balance.

3. Inspection reports with dated photos

This is the one that cost me. In my second case the tenant had let an unauthorised cat ruin the carpet and the side of a sofa, the place needed professional cleaning, and there had been meth use in the unit. The body corp billed me about $2,400 plus GST for decontamination. My insurance would have covered the meth contamination, but only if I could produce inspection records, and I did not have them, because the tenant had dodged every inspection I tried to arrange: erratic work schedule, unavailable, no-shows. The one time I got in, there was heavy incense burning to mask the smell and the cat had been hidden.

Lesson: a tenant who is actively avoiding inspections is itself a red flag, and the absence of records is what hurts you later. Inspect on a regular cadence (the RTA allows once every 4 weeks, with at least 48 hours' written notice, between 8am and 7pm), keep the dated photos, and if a tenant refuses three in a row, that is a Tribunal application of its own.

What to keep: a report for each inspection, dated, with photos of each room and anything of concern. Same angles each time so a change is obvious.

4. Move-in and move-out condition comparison

The cleanest evidence an adjudicator sees in a damage claim is a before-and-after at the same angle. Without a move-in record you are trying to prove a negative, that the damage was not already there, and the burden of proof is on you as the person bringing the claim. Landlords routinely lose damage claims that are entirely genuine simply because there was no starting photo to compare against.

Take a full condition report at the start of every tenancy, get the tenant to sign it, and take the matching set at the end.

5. Every written message, unedited

Adjudicators read messages exactly as written. Keep the emails, texts, and app messages, and do not tidy them up, not even to fix a typo. The back-and-forth often establishes the timeline better than anything else: when you raised the issue, what the tenant said, when they stopped responding. In my arrears case the tenant simply went silent, and the record of me trying to reach them, with no reply, told that story on its own.

6. Quotes and invoices for what you are claiming

This is where "reasonable" matters. The Tribunal awards what you can justify, not what you are upset about. "The place was trashed" is not a claim. "14 spots of cat urine through the lounge carpet, $X professional clean quote, $Y replacement quote for a carpet at the end of its reasonable life" is a claim. Bring the actual quote or invoice for each line, and understand that betterment applies: you do not get a brand-new carpet paid for in full if the old one was halfway through its life.

Walking in with a sensible, itemised number does more for your credibility than any amount of argument. The adjudicator can see you are not chancing it.

7. The notices you served, with proof of service

If your application turns on a breach (rent arrears, a 14-day notice to remedy, a termination notice), bring the notice itself and proof of when and how you sent it. A notice you cannot prove you served is a notice that did not happen, as far as the Tribunal is concerned.

Bring three printed copies of everything

One for you, one for the adjudicator, one for the respondent, even if the respondent does not show. Print it. Do not offer to show a photo on your phone. In both of my cases the tenant did not turn up, and the adjudicator still went through each claim carefully and wanted the document in hand before awarding it. A no-show does not mean a rubber stamp.

A warning: do not let AI draft your application

It is tempting to paste your situation into ChatGPT and have it write the whole submission. Do not. A OneRoof report this year described an avalanche of AI-drafted disputes already clogging the Tribunal's caseload: a leaking tap turning into a five-page complaint, simple rent-arrears cases stretching from three or four weeks out to around two months because the material is longer and more complex. We wrote about that trend in tenants using ChatGPT for disputes.

There are two real risks. First, language models hallucinate: they invent case citations, misstate the RTA, and confidently assert figures that are not in your records. An adjudicator spots a fabricated reference or a number that does not match your ledger immediately, and the moment they do, your credibility is gone for the whole hearing. Second, volume is not strength. A long AI-generated narrative does not beat a clean, complete record; it buries the few facts that matter under padding the adjudicator has to wade through.

A clean and complete record wins every time against an AI-drafted complaint. Use a tool to keep the record correct and to assemble it. Do not use one to write your argument for you. The chronology and the justification should be your own words, short and matched to your evidence.

If the tenant applies against you

Most of this article assumes you are the one filing. But the same record is what defends you when a tenant takes you to the Tribunal, and that situation is more common than landlords expect: a disputed bond deduction, a claim the property was not up to Healthy Homes standard, an allegation you entered without proper notice, or that a notice was retaliatory or a rent increase was invalid.

The good news is that you do not prepare differently. When you are the respondent, the adjudicator is still deciding on dated, specific records, and the burden often shifts to whichever party made the claim. What wins is the same clean history:

• Bond not lodged or lodged late? Your lodgement reference and the date it was lodged answer it on the spot.
• Failure to maintain or a Healthy Homes complaint? Your inspection reports, compliance records, and the log of maintenance requests and completed repairs show what was done and when.
• Entry without notice? The record of the notice you sent and the date shows you stayed inside the 48-hour rule.
• Retaliatory or invalid notice? A dated communication log and the notice itself establish the real timeline and reason.
• Rent increase challenged? The rent schedule with effective dates and the notice you served show the 60-day notice and the 12-month gap were honoured.
• Bond deductions disputed? The move-in and move-out condition comparison, with quotes, is your evidence that the damage was real and the amount reasonable.

A landlord who can produce a tidy, dated record looks organised and credible even when accused; a landlord reconstructing it from memory looks the opposite, regardless of who is in the right. Keeping the record from day one protects you in both directions: it is the case you bring and the defence you raise.

What I did with all this afterwards

After the second hearing, I had a clear picture of what actually wins: a rent ledger that ties out to the period, dated inspection evidence, an itemised claim with quotes, and a justification ready for each line. The problem is that assembling it by hand, after the fact, is slow and easy to get wrong, and the one time you need it is the worst time to be reconstructing it.

So I built it into the tool I run my own properties on. RentManager keeps the rent ledger as you go, with FIFO payment allocation and partial payments tracked period by period, so the arrears figure is correct and exportable on demand. Inspection reports come out as dated PDFs. The communication log is preserved. And there is a Tribunal evidence pack that pulls the arrears schedule, the inspection records, and the correspondence into one set, formatted the way an adjudicator reads it.

The point is not that you will end up at the Tribunal. Most tenancies never do. The point is that if it happens, the evidence is already correct, already dated, and already defensible, instead of something you scramble to rebuild while you are stressed and out of pocket. That is the difference between walking in hoping, and walking in prepared.

See it on your own property

You do not have to take my word for how it looks. Add one of your own properties to the RentManager demo, record a couple of rent payments, and export the rent ledger and an inspection report. That is the evidence set, on your data, in about two minutes. If you are ever standing in front of an adjudicator, that is what you want to be holding.

Frequently asked questions

What evidence do I need for the Tenancy Tribunal in NZ?

Start with the signed tenancy agreement, which establishes the parties, the rent, the term, and each side's obligations - it is the foundation everything else hangs off. Then add dated inspection reports with photos, a move-in and move-out condition comparison, all written communication with the tenant, quotes or invoices for anything you are claiming, and copies of any notices you served with proof of service. A rent ledger matters most when rent is in dispute; if your case is about damage, entry, or a notice and rent was always paid, you do not need one. The adjudicator decides on what you can show, not on what you assert, so dated and specific beats lengthy and vague.

Is a bank statement enough proof of rent arrears?

No. A bank statement shows money arriving but not what the rent was supposed to be each period, so the adjudicator cannot tell a short payment from a full one without doing the arithmetic, which they will not do. Bring a rent ledger that lists the expected rent and the payment received for each period, with a running balance. The arrears figure should be a number the adjudicator can read straight off the page.

Do I need to print my evidence or can I show it on my phone?

Print it, and bring three copies: one for you, one for the adjudicator, one for the respondent, even if the respondent does not turn up. The adjudicator wants the document in hand. Showing a photo on your phone slows the hearing and reads as unprepared.

What happens if the tenant does not show up to the hearing?

The adjudicator usually runs the hearing anyway and rules on the merits. A no-show is not an automatic win. In both of my cases the tenant did not appear, and the adjudicator still went through each claim carefully and wanted the evidence before awarding it. You still have to present your case as if they were there.

How much does it cost to apply to the Tenancy Tribunal?

The application fee is $28 per application (since 1 July 2025), flat regardless of how much you are claiming. You are offered free mediation first, and most rent and bond cases settle there rather than going to a hearing.

What do I do if a tenant takes me to the Tenancy Tribunal?

You defend with the same evidence you would use to bring a claim, so a clean record is both sword and shield. If the tenant disputes a bond deduction, show the move-in and move-out condition reports and the repair quotes. If they claim the property was not maintained or breached Healthy Homes, show your inspection reports and the maintenance and repair log. If they allege entry without notice or a retaliatory notice, show the dated record of the notice you served. The adjudicator decides on dated, specific records regardless of who applied, so a landlord who can produce a tidy history looks credible even when accused.

Should I use ChatGPT or AI to write my Tribunal application?

No. AI-drafted submissions are already clogging the Tribunal's caseload and are the surest way to lose if not done properly. Language models hallucinate fake case citations and misstate the RTA, and the moment an adjudicator spots a fabricated reference or a figure that does not match your records, your credibility is gone. A long AI narrative also buries the facts that matter. A clean, complete record wins every time against an AI-drafted complaint, so keep the chronology in your own words and let your evidence carry it.

Can RentManager produce evidence for the Tribunal?

Yes. RentManager keeps the rent ledger as you go (with partial payments tracked period by period), produces dated inspection PDFs, preserves the communication log, and bundles an arrears schedule, inspection records, and correspondence into a Tribunal evidence pack formatted the way an adjudicator reads it. You can try it on your own property in the demo.
