A good proportion of the population live here, Auckland has long called itself the Polynesian capital.
Plenty of Tongans live in Australia and the United States too but when they live here they are still in Polynesia.
Their league and their supporters are on a mission tonight.
Having beaten the Kiwis here in last year's World Cup, only to stumble against England in the semifinals, they badly want the Kangaroos' scalp tonight.
Win or lose, they will vent their emotions around the city afterwards and good for them.
It's their city, they make us a place larger than we would otherwise be.
We have Kiwis such as Jason Taumolo who chose to play for Tonga and good on him.
He extends our loyalties, proves New Zealand embraces the islands it supports and gives us a stake in tonight's game.
Go Tonga.
