A minimum of Sixth Form Certificate or NCEA-equivalent biology is required. However, people over 20 years old can apply for the Diploma in Dental Hygiene course if they have recently passed the equivalent of a Sixth Form Certificate, or the NCEA equivalent.

Skills are developed on the job. Under the Health Practitioners Competence Assurance Act 2003, dental hygienists are required to attend and participate in continuing professional development. To retain an Annual Practising Certificate, dental hygienists must complete 30 hours of professional development each year.

Dental hygienists are also encouraged to become members of the NZ Dental Hygienists' Association.

Experience as a dental receptionist, dental assistant or dental therapist is useful.
