Buyer's guide — New Zealand

The property due-diligence checklist, in the order that protects you.

Most buyers run the right checks in the wrong order: the slow ones started too late, and the expensive ones spent on properties the cheap checks would have killed. The list below is the one we work from every day. The order matters more than the list.

The rule
Cheapest first. Slowest started earliest.

An $8 title search can kill a deal before you spend $375 on a LIM. A LIM can kill it before you spend hundreds on a building inspection. And because the council's clock on a LIM is up to ten working days, it gets ordered on day one, not when you remember it. Run cheap checks to decide whether the expensive ones are worth buying, and start the slow ones before everything else.

01

Read the record of title, before you fall for the house

$8Instant, online

Everything else sits on top of the title. Order it from Toitū Te Whenua (LINZ) for $8 and read it before you get emotionally committed: who owns it, the estate type (freehold, leasehold, cross-lease, unit title), the land area and legal description, and every registered easement, covenant and mortgage. For another $8 the historic title shows how those interests accumulated.

What you are looking for: rights of way across the land, covenants that restrict what you can build, easements that carry a neighbour's water or power across the section, and a cross-lease flats plan where the drawn footprint no longer matches the house that is standing.

The trap: a block marketed as private can carry legal access rights for the neighbours, and services that depend on land you will not own. We have seen both on one title. The marketing will not mention them; the title cannot hide them.

Run the free public layers

$0One evening

Before paying anyone, the public record will answer more questions than most buyers ever ask it:

  • Council GIS: the zone and what it permits, flood extents, natural-hazard overlays, liquefaction classifications where mapped, noise and airport overlays.
  • The regional contamination register: in Canterbury, Environment Canterbury's Listed Land Use Register issues property statements at no charge. A former orchard, workshop or fuel site on the record changes the conversation, and an entry marked "not investigated" means nobody has ever tested the soil.
  • The rating valuation and its history: not what the house is worth, but how the council's view has moved, and how the value splits between land and buildings. Buildings are the half that wears out.
  • School enrolment zones: point-checked, not taken from the listing.
The trap: an empty result is only good news if the layer was actually queried correctly. When we run these checks we control-test every layer first, because an empty result and a broken query look identical.

03

Order the LIM on day one

Council-set fee (Auckland: $375)Up to 10 working days

The Land Information Memorandum is the council's own file on the property: consents and permits it knows about, hazard information it holds, rates, drainage, and notices attached to the land. The law gives a council up to ten working days to issue one, and that clock is why this step is here and not later: if your offer is conditional, the LIM has to land inside your condition period, so it gets ordered the day the clock starts. Fees are set by each council; Auckland currently charges $375, or $506 urgent.

The trap: treating the LIM as the full story. It reports what the council knows; unconsented work is defined by not being in the file. That is what steps 04 and 05 are for.

Pull the council property file and reconcile it against the house

Varies by councilDays

The property file is the paper trail: building consents, plans, and code compliance certificates. The exercise is reconciliation: walk the property against the file. The second storey, the sleepout, the plumbed-in pool house, the pool fence: each either has its consent and its CCC, or it is your problem the day you settle.

The trap: a vendor pack that runs to two documents. A thin pack is not neutral; it is a finding. Ask, in writing, for the certificates the file should contain.

A building report to NZS 4306, matched to the era of the house

Obtain quotesDays, book early

The standard pre-purchase inspection is a visual inspection to NZS 4306:2005. Use an inspector who works to that standard, carries current indemnity insurance, and belongs to a recognised body. Government guidance points to Building Officials Institute of New Zealand or NZ Institute of Building Inspectors membership. Then match the scope to the era: official guidance flags plaster-style monolithic cladding from the 1980s to the mid-2000s, and on a plastered home of that era a standard visual report is not sufficient. Commission a weathertightness-specific inspection with moisture readings.

The trap: the ex-builder mate. Consumer Protection's words, not ours: "Think twice about using an ex-builder mate." No standard, no insurance, no recourse.

06

Price the insurance before you go unconditional

$0 to askDays

Your insurer reads the same flood maps you found at step 02, and prices them. Natural hazards cover (NHCover) comes automatically with a fire-inclusive home policy, but it is capped: currently $300,000 plus GST for the building under the Natural Hazards Insurance Act 2023. Everything above the cap is your private insurer's decision, which makes insurability and premium a live pricing question on flood-mapped or hazard-overlay land, not an after-settlement errand. Get a real quote on the actual address before your conditions expire.

The trap: assuming the current owner's policy proves anything. Insurers re-underwrite at sale, and what was insurable in 2015 is not automatically insurable on today's flood maps at today's premium.

07

Unit title or cross-lease? Add the extra layer

Disclosure + recordsDays

On a unit title, the seller must give you a pre-contract disclosure statement, and the body corporate's records are part of your due diligence: minutes, the long-term maintenance plan and its fund, levies, and any remediation talk. Read the minutes for the building's future, not its past. On a cross-lease, go back to step 01: the flats plan is the property, and an extension that is not on the plan is a defect in the title itself.

The trap: reading the levy and skipping the maintenance plan. A low levy on a building with an underfunded plan is not cheap ownership; it is a deferred invoice.

Your lawyer, before you sign, and everything above before an auction

Fee-basedBefore signature

The standard TLANZ/REINZ Agreement for Sale and Purchase (currently in its eleventh edition) is a lawyer's document, and conditions are drafting, not box-ticking: finance, LIM, building report, and a due-diligence clause where warranted, each with dates the slow checks above can actually meet. That is the quiet payoff of running this list in order: your condition periods are set by someone who knows the LIM takes ten working days.

And the auction rule: bidding is unconditional. Every check on this page happens before auction day or it does not happen, which is why auction campaigns are where ordered due diligence earns its keep.

The trap: signing "subject to a quick look at the LIM" timeframes a lawyer was never shown. Conditions drafted after the emotional commitment are conditions drafted badly.

Where a research report fits

We run the public-record half of this list, and point the rest.

A Current Analytics report does steps 01 and 02 the way they should be done — the title read in full, every layer control-tested, the valuation history, comparable sales each against their own rating value — and then tells you which of the paid checks matter most on this property, in what order, and what each one needs to answer. It does not replace the LIM, the building report or your lawyer. It makes sure the money you spend on them is spent on the right property, with the right questions.
