The first new Dunedin citizens of 2012 included immigrants from Samoa, Scotland, England, Brazil, Fiji, China, Korea, Canada and the Netherlands.
"Our Maori history goes back more than 1000 years, but we are still a young country, with an increasingly diverse culture," Dunedin Mayor Dave Cull said.
The new citizens were presented with a kowhai "symbolising the putting down of roots in your new country", Mr Cull said.
The Baker family, from the Scottish borders, south of Edinburgh, arrived in Dunedin nearly seven years ago, but the ceremony was "an important part of becoming New Zealanders", musician Paul Baker said.
"We came here for a better and easier life and we got it," he said.
"The pace of life is a lot better here than back in Scotland. Life is a lot quicker there."
Mr Baker's wife, Wilma, works as a nurse at Dunedin Hospital, while their elder son, Gary, is a diesel mechanic at Goughs Cat and younger son, Ewan, a pupil at Bayfield High School.
