If you've ever ordered a survey plan for a New Zealand property and stared at it wondering what all the lines, numbers, and symbols mean — you're not alone. Survey plans are essential property documents, but they can look like a foreign language if you don't know what to look for.
This guide breaks down how to read a survey plan, what each element means, and when you actually need one.
What Is a Survey Plan?
A survey plan (also called a cadastral plan or DP plan) is an official document that shows the precise boundaries, area, and dimensions of a piece of land. It's created by a licensed surveyor and lodged with the official land registry as part of the subdivision or land definition process.
In New Zealand, survey plans are identified by a DP number (Deposited Plan) — for example, DP 123456. This number appears on your Record of Title and is the key reference for ordering the plan.
Why Survey Plans Matter
Survey plans are critical for several reasons:
- Boundary disputes — They define exactly where your property starts and ends
- Subdivisions — They show how land has been divided into new lots
- Easement definitions — They show the precise location and dimensions of rights of way, rights to convey electricity, and other easements
- Building consent applications — Councils require them to verify setbacks and site coverage
- Fencing disputes — They establish legal boundaries for fence placement
- Property purchases — They reveal if structures encroach over boundaries
Ordering a Survey Plan (SP/RP) for $49.90 is one of the smartest things you can do before buying, building, or fencing.
The Anatomy of a Survey Plan
Let's break down the key elements you'll find on most New Zealand survey plans:
1. Title Block
The title block is usually in the bottom-right or top-right corner and contains: - Plan number — e.g., DP 123456 - Survey type — e.g., Subdivision, Easement, Land Covenant - Council/district — e.g., Auckland Council, Wellington City - Surveyor's name and firm — the licensed professional who prepared it - Date of deposit — when the plan was officially lodged - Approval stamp — from the Survey Board of New Zealand2. Lot Numbers and Boundaries
Each parcel of land on the plan is labelled with a lot number (Lot 1, Lot 2, etc.). The boundaries are shown as solid black lines. Key details include:- Boundary lengths — Each boundary segment shows its length in metres
- Bearing angles — Directions shown as degrees/minutes/seconds (e.g., 45°30'15")
- Area — The total area of each lot in hectares (ha) or square metres (m²)
- Street frontage — The length of boundary along a road
3. Easement Areas
Easements are shown as hatched or shaded areas on the plan, often with a dashed outline. Each easement is labelled with: - Easement type — e.g., "Right of Way", "Right to Convey Electricity" - Easement identifier — e.g., "Easement A" or "Easement Area A" - Grantor and grantee — which lots benefit from and are burdened by the easement - Dimensions — width and length of the easement areaThis is one of the most important sections to check — an easement you didn't know about can affect where you build, park, or even walk on your own property.
4. Building Outlines
On some survey plans (particularly newer ones), you'll see building outlines showing the footprint of existing structures. These help identify: - Setbacks from boundaries - Potential encroachments - Site coverage calculations5. Street and Road Details
Roads are shown with their legal name and width. The road boundary is typically a thicker line than internal lot boundaries. If a lot has road frontage, the frontage length will be shown.6. Reference to Other Plans
Survey plans often reference other documents: - Parent title — the title that was subdivided - Head title — the original title from which all lots were created - Amalgamation conditions — requirements that lots must be held together - Consent notices — references to conditions under the Resource Management ActCommon Survey Plan Types in NZ
| Plan Type | Code | What It Shows |
|---|---|---|
| Deposited Plan | DP | Subdivisions, lot layouts, easements |
| Survey Office Plan | SO | Older survey plans, often pre-digital |
| Māori Land Plan | ML | Māori land subdivisions |
| Land Transfer Plan | LT | Plans lodged under the Land Transfer Act |
When you order a Survey Plan for $49.90, you'll typically receive the DP plan along with the title sheet — the part of the Record of Title that shows the plan diagram.
How to Match a Survey Plan to Your Title
Here's the step-by-step process:
- Find the DP number on your title — It appears in the legal description, e.g., "Lot 123 DP 456789"
- Order the survey plan — Use the DP number to request the plan
- Locate your lot — Find Lot 123 on the plan
- Check boundaries and dimensions — Verify they match what you see on the ground
- Review easements — Check if any hatched areas affect your lot
- Compare with fencing or structures — Look for encroachments

Red Flags to Watch For on a Survey Plan
When reviewing a survey plan, look out for these common issues:
Encroachments
If a building or fence on a neighbouring property crosses the boundary line shown on the plan, that's an encroachment. This can lead to disputes and may need legal resolution.Unexpected Easements
A right of way easement across your property means others have the legal right to use that strip of land. Check the plan carefully — you may not be able to build or fence in that area.Amalgamation Conditions
Some plans include conditions requiring lots to be held in the same title. This means you can't sell one lot separately without first applying to remove the condition.Restricted Areas
Consent notices referenced on the plan may restrict what you can build, how high, or where on the site. Always read these in full.Discrepancies Between Title and Plan
If the area shown on your title doesn't match the plan, or if boundary dimensions differ from what's on the ground, you need to investigate. A Guaranteed Search for $45.90 provides official, guaranteed accuracy.When You Definitely Need a Survey Plan
- Before buying a property — Know exactly what you're getting
- Before building or renovating — Confirm setbacks and site coverage
- Before fencing — Avoid boundary disputes with neighbours
- When subdividing — Required by council as part of the consent process
- When resolving a boundary dispute — The official plan is the legal reference
- When an easement is mentioned on your title — See exactly where it runs

Understanding Bearings and Distances
Survey plans use bearings (directions) and distances (lengths) to define boundaries:
- Bearings are measured from North, clockwise: e.g., N45°30'15"E means 45°30'15" east of north
- Distances are shown in metres along each boundary segment
- Areas are calculated from these measurements and shown per lot
You don't need to be a surveyor to read a plan — but understanding that bearings start from North and go clockwise helps you orient the plan to the actual property on the ground.
