This layer identifies critical survey marks which LINZ requires to be physically protected.
Thousands of vital survey marks exist in New Zealand. Many of them are below or at ground level and not noticed by most of us.
People involved in construction work are responsible for making sure survey marks are not damaged. When building works have the potential to destroy existing cadastral and geodetic marks, LINZ needs to be notified so that it can assess whether the marks should be reinstated or replaced.

Please note there may be other important survey marks not identified on this layer, and that LINZ recommends consultation with a Licensed Cadastral surveyor before any construction or earthworks begin.
If you notice a damaged survey mark, you can report it to LINZ by filling out a form on this website
