A strong due diligence process in New Zealand is about confirming one thing: what you’re legally allowed to do, what the site can physically support, and what hidden costs or constraints could derail programme and feasibility. For residential development and renovation, the core documents are the LIM and the Record of Title, supported by a buildability-focused checklist.
Start with the Record of Title: what you legally “own” and what binds the land
A Record of Title is the electronic land record that proves ownership and shows rights and restrictions affecting the land.
You can order digital land records through LINZ’s Land Record Search process.
When you review the title, pay attention to:
- Estate type (freehold, leasehold, unit title, cross-lease)
- Interests registered on the title (mortgages, easements, covenants, notices, etc.)
- Instruments referenced (these often contain the detail that actually matters)
Covenants and easements: the “silent rules” that can break yield or design
Covenants are a common reason a site that looks “perfect” on zoning still can’t be developed the way you expect. LINZ guidance explains how land covenants are noted/recorded on the register and the legal basis for them.
In practical terms, covenants and easements can restrict or shape:
- where you can build (setback-style restrictions or building platform constraints)
- whether you can add a second dwelling or subdivide
- what materials/appearance standards apply (common in newer subdivisions)
- service corridors (drainage, power, access rights) that affect site layout
Tip: don’t stop at the title “summary”. Make sure your lawyer pulls and reviews the actual instruments referenced on the title so you see the exact wording.
The LIM: what Council knows about the property (and what that implies)
A LIM is one of the fastest ways to surface council-held information that can affect feasibility: recorded consents, drainage records, known hazards, and property-specific notes.
For Hamilton, Hamilton City Council advises a LIM typically takes up to 10 working days, and an Express LIM (residential only) can take up to three working days.
Hamilton also has a broader “Land information” page explaining what LIMs are and what councils hold.
If your site is outside Hamilton city boundary, Waikato District Council provides its own LIM ordering pathway (process differs by council).
Hamilton/Waikato-specific due diligence note: hazards information is becoming more prominent
Hamilton City Council notes that from October 2025, LIMs are required to include natural hazards information (or links to regional-council-held hazard information), including flooding, erosion, slope instability, coastal inundation/sea level rise, subsidence, and earthquake/liquefaction risk.
For developers, this matters because hazards can change:
- minimum floor levels and foundation design assumptions
- stormwater strategy and site coverage
- consenting risk and conditions
- insurance appetite and buyer perception
Buildability checks: the practical layer beyond LIM + Title
Once legal constraints are clear, the next step is confirming whether the concept is physically and commercially buildable. For Waikato/Hamilton projects, these are the checks that most often protect margin:
- Services capacity and connection scope (stormwater, wastewater, water supply, power/fibre)
- Stormwater strategy early (soakage vs detention vs network connection; overland flow paths)
- Ground conditions (clay soils, subgrade preparation, drainage performance)
- Access and manoeuvring (driveway gradients, visibility splays, fire access expectations)
- Existing consent history (unconsented work risks; missing sign-offs can complicate sale/finance)
A simple due diligence checklist you can reuse
Before you commit to purchase or finalise concept design:
- Order the Record of Title and review estate type + interests + referenced instruments.
- Identify any covenants/easements and have the instruments reviewed (not just the title summary).
- Order the LIM from the relevant council (Hamilton / Waikato District as applicable).
- Run a services + stormwater reality check before locking yield (civil engineer input early pays for itself).
- Treat hazards and site constraints as feasibility inputs, not “later-stage details”.
