"We have the police dogs and their handlers coming this afternoon and everyone is looking forward to that."
Kindergarten families had provided Samoan food such as sapasui (Samoan chop suey), panikeke (doughnuts) and taro dishes.
Police officers Keith (Tomo) Thomson, Jake Bone and Colin Wright were enjoying some time at the kindergarten.
"We got a really nice welcome from the children and it's nice to be invited," said Wright.
The celebration was one of the hundreds held in schools and workplaces during the week.
The theme for Samoan Language Week 2018 has been "Alofa atu nei. Alofa mai taeao - Kindness given, Kindness gained.''
Samoan is the third-most spoken language in New Zealand and Samoan people are the largest Pasifika group in the country.
