In September 2023 I was called to a lifestyle block outside Lincoln to find out why the septic system had stopped. The answer was a crushed distribution pipe and a disposal field driven over by a tracked chipper. The owner had hired two men with a ute to take down eight macrocarpa along the shelterbelt at NZ$600 a tree, cash. They had dropped the trees where they stood, driven the chipper across the disposal field to get at them, left the stumps, and gone. Repairing the field cost NZ$7,400. The macrocarpa work, done properly, would have cost perhaps NZ$9,000 to NZ$12,000. He saved about NZ$5,000 on the trees and spent it on my trench, which is the arithmetic of hiring tree work badly.
Insurance, and the piece of paper that proves it
Tree work damages things. Limbs land on fences, tracked machines cross drains and driveways, a felling cut goes wrong and a trunk hits a shed. Anyone doing it should hold public liability cover, and NZ$1 million is the floor; NZ$2 million to NZ$5 million is normal for a business that works around houses. Ask for the certificate of currency, a one-page document from the insurer showing the policy limit and the expiry date. A verbal “yes, fully covered” is not a certificate. Some policies exclude work above a certain height, work near power lines, or the use of cranes; if the job involves any of those, ask directly.
Qualifications that mean something
New Zealand does not license arborists the way it licenses drainlayers or electricians, which is why I have to be authorised to dig up your sewer while anyone at all can offer to fell your tree. What exists instead is a set of qualifications and tickets.
- The New Zealand Certificate in Arboriculture at Level 4 for climbers and ground staff, and Level 5 or 6 for anyone assessing trees or writing reports.
- Current chainsaw and, where used, elevated work platform tickets, which are unit standards with a certificate behind them.
- For work near power lines, the Electricity (Safety) Regulations set minimum approach distances, and only a contractor approved by the lines company may work inside them.
- Membership of the New Zealand Arboricultural Association, which is voluntary but comes with a code of ethics and a complaints process.
Tree work is also high-risk under health and safety law. Where a climber will be working more than 5 metres above the ground, or a tree is being felled commercially, the work is notifiable and WorkSafe New Zealand should have been told at least 24 hours before it starts. A contractor who has never heard of this is telling you something.
What a written quote should itemise
A price on the back of a card is not a quote. In Canterbury a straightforward removal of a 12-metre tree with good access runs NZ$1,500 to NZ$4,500; a large macrocarpa or pine over buildings NZ$5,000 to NZ$12,000; a crane job can pass NZ$15,000. Crown reduction on a mature tree is NZ$600 to NZ$2,000. Within those ranges, the number is only meaningful if the document says what it covers.
- Each tree, identified by species and position, and what is being done to it: removal to ground level, reduction by a stated percentage, or specific limbs.
- Stump grinding as a separate line, typically NZ$150 to NZ$500 per stump, or a statement that stumps remain.
- Access and machinery: whether a tracked chipper or an excavator is coming onto the section, and where it will travel. This is the line that would have saved the Lincoln disposal field.
- Services location. Underground power, water, gas and drainage marked before any machine arrives; the beforeUdig service costs nothing.
- Traffic management if any part of the work reaches a road, at NZ$800 to NZ$2,000 a day for an approved plan and cones.
- Waste: green waste chipped and removed, chipped and left as mulch, or logs left as firewood, with the difference in price shown.
- Consent status. Whether the tree is on the Significant Trees schedule or in a protected area, who has checked, and who applies if consent is needed.
- Clean-up, GST, payment terms and the date the price expires.
The red flags
Door-knockers in the week after a nor’wester or a snowfall. Anyone who offers to “top” a tree, which is not pruning; the difference is laid out in what happened with crown reduction versus topping on a Hamilton East oak. Cash-only pricing. A price for the whole shelterbelt with no per-tree breakdown. No mention of where the machines will drive. Anyone who says a scheduled tree is “no problem” without having looked it up. I have dug up the aftermath of every one of these.
Frequently asked questions
How much does tree removal cost in Canterbury? NZ$1,500 to NZ$4,500 for a medium tree with good access, NZ$5,000 to NZ$12,000 for a large tree over buildings, and more where a crane or traffic management is needed. Stump grinding is usually extra at NZ$150 to NZ$500.
Do arborists need a licence in New Zealand? No. There is no licensing scheme for arborists; qualifications, insurance and association membership are voluntary. That is why checking the certificate of currency and the qualification matters more than in a licensed trade.
Should I get more than one quote for tree work? Yes, at least two, and compare what each one itemises rather than the bottom line. A cheaper price that leaves stumps, drives machinery over drains and skips the consent check is not cheaper.
