Who Is Responsible When an Auckland Council Tree Causes Damage?

The Legal Issues at the Centre of the Dispute

Several legal principles are engaged when a council-owned or council-controlled tree causes damage.

1. Responsibility for Council-Owned Assets

Where a tree is confirmed to be on public land, Auckland Council (or Auckland Transport, depending on the corridor) is responsible for managing it. That responsibility includes:

• Ongoing maintenance
• Managing foreseeable risks
• Responding appropriately when damage is occurring or likely to occur

Prolonged uncertainty over land ownership, as occurred here, can itself become relevant when assessing whether Council acted reasonably.

2. Damage to Private Property and Infrastructure

The reported damage goes beyond cosmetic issues. The tree’s roots are alleged to have:

• Lifted and cracked a concrete driveway
• Displaced a water meter box
• Caused a water leak and increased water charges

Where Council infrastructure or assets interfere with private property, affected owners may have potential claims grounded in negligence, nuisance, or failure to properly maintain a public asset, depending on the facts.

3. Protected Trees and the Limits of Council Discretion

The tree in question is protected under the Auckland Unitary Plan, meaning removal would require resource consent and is treated as a last resort.

However, protection does not grant absolute immunity. Even protected trees must be managed in a way that does not unreasonably damage private property or create safety risks. Where damage is ongoing and unavoidable, councils must still consider mitigation options, including engineering solutions or, in limited cases, removal.

What Legal Options Do Ratepayers Have if Council Engagement Fails

For homeowners facing similar Auckland Council tree disputes, several escalation pathways may be available.

1. Formal Review and Written Decisions

Ratepayers should request clear, written confirmation of:

• Land ownership
• Asset responsibility
• The basis for any compensation offer
• Whether damage is accepted as being caused by the council tree

Clear documentation is critical if the dispute escalates.

2. Complaint to the Ombudsman

If council processes are prolonged, inconsistent, or unreasonable, a complaint to the Office of the Ombudsman may be appropriate. The Ombudsman can investigate maladministration, including unreasonable delay or poor decision-making.

3. Legal Action Through the Courts

In some cases, affected owners may pursue:

• A negligence or nuisance claim where damage is ongoing and foreseeable
• Judicial review, where the issue is not the outcome itself but whether Council followed a lawful and reasonable process

This may be particularly relevant where evidence (such as surveys or expert reports) is ignored or inconsistently applied.

4. Risk and Liability When Homeowners Act Themselves

This case also highlights a common dilemma: homeowners may be reluctant to repair damage for fear of disturbing roots, damaging a protected tree, or assuming liability if something goes wrong.

This risk underscores the importance of obtaining clear written approvals before undertaking any work near a council-controlled tree.

A Wider Issue for Auckland Ratepayers

Disputes involving Auckland Council trees are not uncommon, particularly where roots affect driveways, pipes, or foundations. This case demonstrates how prolonged uncertainty, modest compensation offers, and the interaction between protected tree rules and property damage can leave homeowners effectively stuck.

Understanding the legal framework—and knowing when to escalate—is often key to breaking that deadlock.
