LINZ Survey Mark Protection & Relocation (Auckland)

Locate, assess, and protect existing LINZ survey marks before earthworks and construction — and manage relocation where it’s genuinely required.

Why mark protection matters

Survey marks underpin boundary definition and construction control. If marks are disturbed, it can create delays, compliance headaches, and (in the worst cases) expensive re-work. We help builders, engineers, and asset owners understand what’s on site, what’s at risk, and what needs to be done to keep the job moving.

What we do

  • Desktop review: identify relevant LINZ marks and likely risk areas from available records and plans.
  • Site location & condition: locate marks, confirm condition, and note constraints (access, traffic, pavement, services).
  • Protection plan: practical recommendations for fencing, offsets, temporary works, and site controls.
  • Monitoring & liaison: support during construction where marks are at ongoing risk.
  • Relocation / replacement: where unavoidable, coordinate the process and set out replacement marks in the correct position.
  • Documentation: clear reporting and plans showing marks found, protected, at risk, or replaced.

Typical situations we help with

Roading and drainage works, retaining walls, driveway upgrades, kerb renewals, subdivision earthworks, and general construction sites where marks sit in pavements, berms, or along boundaries.

FAQs

A LINZ survey mark is a physically placed mark (often in concrete, kerb, or ground) that supports cadastral boundaries and survey control. Marks are used to re-establish boundaries and provide reliable reference for future work.

In general, no — survey marks are legally protected and should not be disturbed. If works will impact a mark, the right approach is to assess options early: adjust design/sequence where possible, or plan a compliant relocation/replacement process where unavoidable.

Stop and get advice early. The impact depends on the mark type, its role in boundary definition/control, and whether it can be replaced in a controlled way. We can assess consequences quickly and coordinate a practical path forward to minimise delays.

Relocation is typically only appropriate when the mark genuinely cannot remain in place due to approved works. We’ll look at practical alternatives first (protection/offsets/sequence), then manage compliant replacement where needed.

Earlier is always cheaper. Ideally, engage before mobilisation so marks can be identified and protected in the site setup. If you’re already on site, we can still help — just expect that access, traffic, and programme constraints may drive effort.
