Arborists gain qualifications to practice arboriculture in a variety of ways and some arborists are more qualified than others. Experience working safely and effectively in and around trees is essential. Arborists tend to specialise in one or more disciplines of arboriculture, such as diagnosis and treatment, climbing and pruning, cabling, utility arboriculture, or consultation and report writing. All these disciplines are related and some arborists are very well experienced in all areas of tree work, but not all arborists have the training or experience to properly practice every discipline.

There are a number of educational providers that offer courses from introductory Level 2 up to diploma Level 6.  Many providers offer courses that fit your circumstances from on the job apprenticeships to full-time courses on campus. A Level 4 Advanced National Certificate is often the minimum qualification required by employees. The following training organisations offer most or all of these qualifications.

TRAQ Course

NZ Arb, in association with the ISA, presents the TRAQ (Tree Risk Assessment Qualification) training course.
This is the new ISA program that was originally called TRACE and that ISA has now taken under the credentialling umbrella and modified to follow the methodologies outlined in the ISA Best Management Practice for Tree Risk Assessment.

NZ Arb expects to run its 3-day TRAQ course at least once a year for the near future in different centres around NZ.

All trainees must have either
