Auckland Council Tree Trimming Guide: Permits & Services

If a street or park tree needs attention, start by reporting it to Auckland Council. If you’re arranging pruning on private land, first check who owns the tree, what protection applies and which branches you want to trim. Council approval as the tree owner and resource consent are separate checks.

How do I ask Auckland Council to trim a street or park tree?

Use Auckland Council’s Report a problem form for a street or park tree that needs attention. Give the nearest address or landmark and describe what you can see, such as a broken branch hanging over a footpath. Add photos from a safe position and keep the reference number if you receive one. Council can assess what action is needed.

If you want to arrange work that would affect a Council-owned tree yourself, check the Tree Owner Approval process before booking a contractor. It covers pruning and work that may disturb roots. Resource consent may also be needed. For removal of a tree on a rural road, check Auckland Transport’s rural road tree approval process.

Do I need resource consent to trim a tree on private land?

It depends on the tree, its location and the work proposed. The position of a fence alone may not tell you who owns a tree near the boundary. Confirm ownership and explain the proposed work before asking Council which rules apply.

  1. Check planning protections. Use the Unitary Plan maps to look for a notable tree or a Significant Ecological Area. Tell Council if the tree is near a stream, wetland or coastal cliff.
  2. Check the property documents. The property file may contain earlier consent conditions. Check the record of title for a covenant or consent notice. See Council’s tree protection and consent guidance.
  3. Describe the whole job. Identify the branches and why they need work. Include any digging, trenching or driveway work near the roots so Council can consider it alongside the pruning.

What if the tree is officially listed as notable?

Under the Auckland Unitary Plan’s Notable Trees Overlay, standard D13.6.1, permitted trimming has several conditions. Two are a branch diameter of no more than 50 mm at the cut and removal of no more than 10% of the tree’s live growth in a calendar year. The work must also follow good arboricultural practice and retain the tree’s natural form and branching pattern. Ask Council whether that standard and any other rules apply to the proposed work.

For a wider explanation of protected trees and removal, see our guide to Auckland’s tree rules.

What if the branches come from next door or are near power lines?

Talk to your neighbour first and check whether the tree is protected. New Zealand Government guidance on overhanging branches says you can generally trim most branches that cross the boundary back to it. If a contractor needs access from next door, agree on that with your neighbour before booking.

If a branch is touching a power line or could reach one during pruning, keep clear and contact your electricity provider for advice. Follow WorkSafe’s guidance on trees near overhead lines.

What to ask an arborist before accepting a quote

Describe the result you want, such as clearance from a roof or more light over a path. Ask which branches will be shortened or removed, who will confirm any approvals, and whether the quote includes taking away the cuttings. Send a photo of the whole tree, the branches in question and the route in from the street.

The International Society of Arboriculture’s guide to pruning mature trees explains why the choice of cut depends on which part of the branch stays. Ask your arborist to explain the proposed cuts and how much canopy will remain.

For work on your property, see Heaven Contracting’s Auckland tree trimming service or tree pruning service. Ask for a written quote with the property address and any Council advice you already have.
