Tree work on a lifestyle block ranges from routine pruning to hazardous removals. Knowing when to call a professional can prevent injury and property damage.
When to call an arborist
- A large tree is within falling distance of your house, shed, or driveway
- Storm damage has cracked or hung up branches
- A tree is leaning suddenly or has lifted roots
- Branches are near power lines — always use a qualified contractor for these
- A tree is dead, dying, or has significant decay
- You need a tree health assessment for a notable or protected tree
What an arborist can do that you should not
- Work at height with ropes and harnesses
- Remove large branches or whole trees near structures
- Work near power lines (with network coordination)
- Grind stumps below ground level
- Assess tree health and structural risk
Safety considerations
- Never use a chainsaw above shoulder height or on a ladder without proper training and equipment.
- Do not attempt to fell a tree within falling distance of buildings, power lines, or stock.
- Hung-up branches (wedge in another tree) are extremely dangerous — call a professional.
- Some Nelson–Tasman councils protect notable trees and certain natives. Check before removing.
Questions to ask an arborist
- Are you qualified and insured for tree work at height?
- Can you work near power lines, or do you arrange that with the network?
- Do you remove or chip the green waste?
- Can you advise on resource consent for protected or notable trees?
- What is your typical lead time?
