Retaining Walls Whangarei and Northland

Retaining Walls we can advise on whether you need a permit for any building work in connection with a retaining wall that:

1# retains not more than 1.5 metres depth of ground; and
2# does not support any surcharge or any load additional to the load of that ground (for example, the load of vehicles).

Guidance on the exemption

This exemption allows a retaining wall (which is any wall constructed to retain or support the surrounding ground) without needing to get a building consent as long as it does not retain more than 1.5 metres (vertically) of ground and it includes ground water drainage in relation to retaining walls.

This exemption does not apply to retaining walls that are subject to any additional load or surcharge, such as:

  • vehicle driveways
  • parking spaces
  • swimming pools
  • buildings
  • other retaining wall(s), or
  • sloping ground above the top of the retaining wall.


Retaining walls with sloping ground

If the ground above the top of the retaining wall is only gently sloping, this may not be considered as ‘surcharge’. To determine the impact of the sloping ground and its pressure on the stability of the proposed retaining wall, you may wish to seek professional advice; for example, from a chartered professional engineer.
