Usually pupils from a local primary school perform waiata at the ceremonies but because the schools have only recently resumed, the new citizens, their friends and family were treated to a performance from the Rotorua Lakes Council Waiata Group.
Mayor Steve Chadwick said she enjoyed having primary schools visit and the school groups had many shades and shapes.
"Your children will be part of that one day," she told the new citizens.
The citizenship ceremony was the second of 2018.
Chadwick said ceremonies would usually be held every six weeks, but there had been two in as many months due to a backlog of people wanting to become citizens.
The next citizenship ceremony will be on March 20.
