NZ Tax Guide for Dental Hygienists (2025-26)
Dental hygienists in New Zealand are registered with the Dental Council of New Zealand. Most are employed in dental practices and paid PAYE wages or a percentage of billings. Some dental hygienists operate as independent contractors, visiting multiple practices, and must manage their own provisional tax and potentially GST obligations.
