"When he qualified he was over the moon," said Sione Fonua.
He'd always been very proud of his Tongan heritage, but spoke only a little of the language.
Fonua had been trained by New Zealander Jon Winter, who was designated head coach for Tonga.
Other New Zealand-born Olympians included Aron Baynes, 25, a basketballer for Australia, who was born in Gisborne. His uncle Ian Barron of Auckland said Baynes' family had moved to Australia when he was 2 or 3 and his excited parents Barbara and Marton would be in London to watch him play.
"The whole family's pretty thrilled for Aron. He has worked very hard," he said.
The other exported Kiwi-born talents are:
Jozef Klaassen, 29, a member of Holland's rowing team, who was born in Thames and left New Zealand several years ago;
Ella Nicholas, 21, a kayaker for the Cook Islands, was also born in Tauranga; Francesca Snell, 25, a water polo player for Britain, who is from Auckland; Joshua Utanga, 24, a kayaker for Cook Islands, who was born here.
Kiwis are helping out behind the scenes, too. Hugh McCutcheon coaches the US women's volleyball team and Jeni Pearce is nutritionist for the British Olympic athletes' pre-games "holding camp".
So when you're that involved with another country's medal hopes, who do you cheer for? Taupo-born Pearce was conflicted: "I want the best athlete to win, but I also want New Zealanders to do really well and they also have a history of punching above their weight," she said.
New Zealand actually imports more athletes than it exports, however: 26 of our 184 athletes were born overseas.
NZ athletes delayed
New Zealand's Olympic athletes have been caught up in the traffic chaos of London after their buses from the airport were delayed.
Just weeks before the Olympic Games begin, embarrassing logistical issues have surfaced including traffic jams, security staff who don't speak English and breakdowns with the telecommunication network.
Chef de Mission Dave Currie said most of New Zealand's athletes arrived this week and had settled in.
He said the arrival was a fairly smooth one except for bus delays from Heathrow Airport.
The Herald on Sunday understands some athletes were stuck on a bus for four hours from the airport to the Olympic Park Village, a route that should take 40 minutes, or an hour on public transport.
