He says while some parents share their Pasifika culture with their children, some don't.
''For a large proportion of our group, this is their first experience of Pasifika or to experience it in a positive setting, So we've done a lot of work around building that pride in being Pasifika and showcasing that for them.''
Pride is a crucial word for Leaia, who says it has been important for the students to be given a safe place to explore who they are as Pasifika people.
''That's the reason we have named our group Nesian Pride,'' he says. ''What people see on stage is a result of all the hard mahi we have put in in terms of finding out about their identity. You are really only able to showcase something you are proud of, so they are going through that journey."
The group has around 70-80 members.
Leaia says Covid-19 restrictions have meant performance opportunities have been thin on the ground.
''We had a fiafia [celebration] night a few weeks ago and we are creating opportunities to perform in school assemblies - but this is a much bigger stage for us to showcase our pride and our culture."
