About
A team that takes trees seriously.
NZ Tree Smiths was founded on a simple idea: that the people doing tree work on a million-dollar property should bring the same level of skill and care as the architects, builders, and landscape designers who came before them. Trees are slow to grow and easy to ruin. Our job is to keep yours healthy, safe, and beautiful for decades — not just to get them out of the way today.
We're qualified arborists, not just chainsaw operators. Every project is planned, briefed, and led by someone who can read a tree the way a builder reads a structural drawing. We work to AS 4373 — the Australian and New Zealand standard for pruning amenity trees — because shortcuts on standards are how trees end up dead five years after the work was done.
We also take the unglamorous parts seriously. Insurance. Site safety. Cleanup. Honest quotes. The reason our clients call us back, and recommend us to their neighbours, is rarely the climbing — it's everything around it.
