An arborist's first site visit is essentially a professional health check for your trees. The arborist will walk your property, assess each tree you're concerned about, and give you an honest picture of what work — if any — is needed. Most initial visits take between 30 minutes and a couple of hours depending on the number and complexity of trees involved.
What the Arborist Will Look At
A qualified arborist doesn't just glance at a tree and give you a price. They carry out a structured visual assessment that typically covers:
- Crown condition — leaf colour, density, dieback, and signs of stress
- Trunk and bark — cracks, cavities, fungal growth, cankers, or unusual swelling
- Root zone — soil compaction, surface roots, signs of root rot, proximity to structures or services
- Branch structure — co-dominant stems, included bark, deadwood, and crossing branches that could fail
- Overall lean and stability — whether the tree poses a risk to people, buildings, fences, or neighbouring properties
They may use a mallet to tap the trunk and listen for hollow sections, or probe soft spots in the bark. For larger or high-value trees, they might recommend a more detailed Level 2 or Level 3 risk assessment as a follow-up, which can involve specialist equipment.
Discussing Your Goals
Before or during the inspection, a good arborist will ask what you're hoping to achieve. Common goals include:
- Removing a dead, dying, or dangerous tree
- Pruning for clearance from a house, power lines, or driveway
- Improving light or views
- Treating a pest or disease problem
- Getting a professional opinion before buying a property
Being clear about your priorities helps the arborist tailor their recommendations. Don't be shy about mentioning budget constraints — a professional will work with you to prioritise the most important work.
Council Consent and Protected Trees
One of the most valuable things an arborist can do on a first visit is flag whether any of your trees are protected under your local district plan. Many councils across New Zealand schedule significant trees, meaning you need resource consent before pruning or removing them — even on your own property.
Your arborist should be familiar with local rules, but always confirm with your council directly. Rules vary significantly between territorial authorities. MBIE Building Performance can point you toward the right contacts if you're unsure where to start.
Separately, some tree work near buildings may intersect with building consent requirements — for example, if root removal could affect foundations. Again, check with your council.
Health and Safety Considerations
Arborists work under WorkSafe NZ guidelines, and a professional will assess site hazards during the visit. This includes:
- Overhead power lines — work near lines is strictly controlled in NZ. Your arborist will liaise with your lines company if needed; this is not something to attempt yourself.
- Underground services — roots near water, gas, or drainage lines require careful planning
- Access and drop zones — where cut material will fall and how equipment will reach the site
Never attempt to prune or remove trees near power lines yourself. This is dangerous and potentially illegal without the right approvals.
What You'll Receive After the Visit
Following the assessment, expect the arborist to provide:
- A clear verbal explanation of their findings on the day
- A written quote outlining the scope of work, method, and price
- Recommendations prioritised by urgency (e.g. immediate safety risk vs. routine maintenance)
- Advice on whether council consent is required before work begins
As a rough guide, quotes for straightforward pruning jobs on a single tree might start from a few hundred dollars, while complex removals involving cranes, traffic management, or protected species can run into several thousand. Always get at least two or three quotes for significant work.
What to Prepare Before the Arborist Arrives
- Know your boundaries — point out where your property ends so the arborist can assess trees accurately
- Unlock access — gates, side passages, and any locked areas near the trees
- List your concerns — write down anything you've noticed, such as recent storm damage, mushrooms at the base, or unusual leaf drop
- Check your district plan — a quick search on your council's website for "scheduled trees" or "notable trees" is worthwhile before the visit
Choosing a Qualified Arborist
In New Zealand, look for arborists who hold a New Zealand Certificate in Arboriculture or are members of the New Zealand Arboricultural Association (NZAA). These qualifications indicate formal training in tree assessment, safe work practices, and industry standards. BRANZ publishes guidance on building and site considerations if you want background reading, though their focus is primarily on buildings rather than arboriculture specifically.
When to Call a Professional
Always engage a qualified arborist rather than attempting tree work yourself if:
- The tree is large, leaning, or showing signs of structural failure
- Any branches are within falling distance of a building, vehicle, or person
- The tree is near power lines
- You suspect disease or pest infestation that could spread
- The tree may be protected under your district plan
You can find qualified, local arborists on tradedirectory.co.nz — it's a good idea to read reviews and confirm qualifications before booking.
