Picking up bronze medals were TeUarangi in kumite, Gould in the 40kg kumite, Imogen in the 10-11 kata and kumite, and Kingi in the 8-9 kata and kumite.
Claiming Whangarei's only individual silver medal was Lafaele-Edwards, with Tana and Ear taking silver in the 10-13 year olds' team kata event.
Whangarei's Miyagi Kan Karate Club sensei Craig Nordstrand said it was pleasing to see his small bunch of kids pick up so many medals and good results.
He said everyone performed admirably and it showed hard work could pay off, no matter the age.
"It is the best results we've had in many years," Nordstrand said. "You get generations that come through - it goes around in cycles sometimes.
"The next best was six years ago and that was when Shane [Tregidga] came through and he's still going. We've got a lovely bunch of kids coming through at the moment ... we didn't lose a final but we had a lot of hard luck bronzes, where they matched up with the eventual winners in the semifinals.
"I think the hard work we've put into the whole thing since the kids put their goals in the start of the year,is helping them reach their goals."
