When to Use an Arborist: The Complete Guide for Tree Care in New Zealand

Trees are one of the most valuable features of any property. They offer shade, beauty, privacy, and a boost in property value. But like any living thing, they need proper care to thrive. And sometimes, they pose risks that require expert attention.

If you're wondering when to use an arborist, this guide will walk you through everything you need to know - from recognising tree issues to understanding the risks of DIY work, and how to choose the right professional for the job.

What is an Arborist?

An arborist is a qualified tree care specialist trained in the science of planting, maintaining, and removing trees safely and correctly. Arborists understand tree biology, structure, growth patterns, and local regulations. They also have the right equipment and training to handle even the most complex jobs.

Unlike general landscapers or handymen, arborists offer long-term tree care solutions that protect both your trees and your property.

When To Use An Arborist

There are several key situations where bringing in a qualified arborist is not just a good idea, it is essential.

1. Your Tree is Showing Signs of Stress or Disease

Discoloured leaves, sparse growth, early leaf drop, fungus at the base, cracked bark, or visible insect damage are all red flags. Arborists can diagnose what is going on and recommend the best course of action. This can save the tree if possible, or ensure it is safely removed if necessary.

2. A Tree is Posing a Safety Risk

Overhanging limbs, deadwood, storm-damaged branches, or trees close to buildings and powerlines are serious hazards. Arborists are trained to assess risk and carry out high-risk removals using proper safety techniques and gear.

3. You Need Specialist Pruning or Shaping

Good pruning improves tree health, structure, and appearance. Bad pruning, or topping, can weaken the tree, trigger aggressive regrowth, or cause long-term damage. Arborists know where to make cuts that encourage strong, balanced growth while preserving the tree’s natural form.

4. Tree Removal is Required

Whether a tree is dead, dying, unstable, or interfering with your property, arborists can remove it safely and efficiently. They will also assess whether removal is necessary and offer alternatives if appropriate.

5. You are Planning Landscaping or Development

Arborists can help you plan your landscape around existing trees, identify species worth preserving, and guide new planting decisions. They can also assess risk of construction-related root damage on protected trees before you build.

6. Emergency Tree Work is Needed

After storms or high winds, broken limbs and fallen trees can pose urgent safety risks. Arborists offer emergency services to safely clear hazards and assess other trees that may be compromised.

7. Preventive Tree Maintenance

Not every call to an arborist is about a problem. Regular inspections and professional pruning reduce risk, promote tree health, and catch issues early. This can save you stress and money over time.

Why Tree Work Should Not Be a DIY Job

Tree work might seem manageable - until something goes wrong. Whether it's an unexpected fall, an incorrect cut, or unseen structural damage, DIY tree jobs often create bigger problems than they solve. Here is why it is better to leave it to the professionals.

1. Lower Risk of Injury and Property Damage

Tree work is dangerous. Our arborists are qualified, experienced, and trained to work at height, near powerlines, and in tight spaces. This means your home, family, and property are in safe hands.

2. We Know Where to Place Cuts (and Where Not To)

A few wrong cuts can compromise a tree's health or make it unsafe. Many homeowners unknowingly remove the central leader or key limbs, making future work more difficult and less safe. Arborists understand tree biology and use best-practice pruning techniques to support long-term tree health.

3. Fully Insured for Peace of Mind

Urban Arborists are covered by $5 million in public liability insurance. That means if something unexpected happens, you’re protected. Every reputable arborist should be insured - and if they are not, that is a red flag.

4. Specialist Equipment Gets the Job Done Right (and Fast)

We have the right tools - from climbing and rigging gear to cranes, chippers and stump grinders - to complete the work quickly and cleanly. You won’t be left with a mess or need to spend your weekend hiring tools and trying to finish the job.

5. We Understand Local Rules Around Protected Species

Some native or significant trees in Auckland are protected by law. Removing or pruning them without consent could lead to major fines. We can tell you what is protected and help you navigate the resource consent process if needed.
