Some addressed the crowd with their stories and how they came to live in New Zealand.
Charlotte Harman, originally from Fiji, was proud to be a New Zealander. "I have lived here for nine years, I moved to make a fresh start in my life. I have lived in Rotorua for five years. It is a pleasure and a privilege to become a New Zealand citizen."
The Homan family from South Africa emigrated to Rotorua in 2007.
Derick Homan said he and his family, wife Charmaine and their sons Pieter and Bryan, were happy with the shift.
"It's the children, they can't play outside in the streets [in South Africa]. Safety is the most important thing for us ..."
"I first decided we were going to come here on a visitor's permit, we had friends close to Whakatane. We wanted to stay for two years, I was offered a job and then we decided not to apply for another permit but to apply for citizenship."
Mr Homan, who is a fitter and turner, arrived in New Zealand on a highly skilled work visa.
He said he was supporting both South Africa and the Black Caps in the Cricket World Cup semifinal yesterday, and would be pleased if either team won, and went on to win the World Cup.
