Scope of practice competencies for orthodontic auxiliaries

This section details the competencies expected from orthodontic auxiliaries in New Zealand.


The Council defines competence as the knowledge, skills, attitudes, and behaviours (‘competencies’) an oral health practitioner must have to practise safely, competently, and professionally in their scope of practice.

This document describes the minimum competencies a practitioner must achieve through their education and training to be registered in the orthodontic auxiliary scope. 

The competencies prescribe the scope of practice for orthodontic auxiliary practice.

The competencies are presented in the following domains:

  • Ngaiotanga - Professionalism
  • Whakawhiti kōrero – Communication
  • Kaiakatanga ahurea – Cultural competence (effective until 31 December 2022)
  • Haumarutanga ahurea - Cultural safety (effective from 1 January 2023)
  • Ngā whakaaro kaikini - Critical thinking 
  • Mōhiotanga pūtaiao me te haumaru - Scientific and clinical knowledge
  • Tiaki turoro-  Patient care.

The competencies broadly describe the knowledge, skills, attitudes and behaviours expected of an orthodontic auxiliary; and are outcome focussed. The learning curriculum will provide the level and extent of detail needed to facilitate graduates’ achievement of these competencies, for registration in the scope of practice for orthodontic auxiliary practice.

Orthodontic auxiliaries practise under the direct supervision of a dentist or orthodontist who is present on the premises at which the work is carried out and who is responsible for the patient’s overall clinical care outcomes.

It is assumed that all competencies are performed with a degree of quality consistent with patient and whānau well-being, and that oral health practitioners can self-evaluate the quality and effectiveness of the care they provide.

There is also a clear link between a number of the competencies and the standards embodied in the standards framework that registered oral health practitioners must meet.
