In 2002, both University of Otago and AUT debuted 3-year Bachelor of Health Science degrees. The Otago degree was endorsed in dental therapy, while the AUT degree was in oral health, but still only allowed for registration as a Therapist. At Otago, this was offered in addition to the 2-year diploma. Both degrees were discontinued in 2007. The current 'dual degree' was introduced at AUT in 2006 and at Otago in 2007. This was in response to a shortage and increased legislative requirements.
