The winners were announced yesterday.
There were more entries in the sustainable architecture category this year and many projects in other categories also featured sustainable principles, judging panel convener John Gray, of Dunedin's Oakley Gray Architects, said.
The entries ranged from a school building which made the judges want to go back to school to a Department of Conservation shelter that reached up to the sky and emulated mountains, and Mr Gray said the judges were impressed with the "extremely high" standard of entries.
The University of Otago's $9.6 million Hunter Centre was Dunedin's first structure designed to meet the Green Building Council's green star rating system for sustainable buildings.
It was a winner in both the sustainable and public architecture categories.
The building featured natural ventilation via high automatic louvres, a pellet burner for heating and rainwater collection for re-use. Sustainable timbers were used and only 20% of the construction waste went to landfill.
In the Queenstown Aquatic Centre, low-emissivity glass and vapour barriers minimise energy loss and condensation, while heat is recovered from exhaust air and used to heat incoming air.
The awards are open to all architect members of New Zealand Institute of Architects practices.
There are eight regional awards and the winners are eligible for consideration for a New Zealand Architecture Award, which will be decided by a national jury, including an international judge, next year.
The overall winner of the New Zealand Architecture Medal will be announced in May.
The Southern judging panel included architects David Stringer, of Queenstown, Jo Case, of Dunedin, and Jamie Gilbertson, who is head of college at the University of Otago's Arana College.
