Auckland showcased in episode of the 'Biggest Loser'

Auckland has been showcased to millions of Americans overnight, during an episode of the 'Biggest Loser'.

An episode of the popular reality series was filmed in the city earlier this year, and it's now gone to air.

It saw 'Biggest Loser' couples having to sprint up the SkyTower, sail an America's Cup yacht and complete a triathlon at Bethells Beach.

Auckland Tourism, Events and Economic Development spokesman Brent Warren says the US is Auckland's third largest visitor market.

"Money can't buy this sort of exposure. The Biggest Loser gives a fabulous profile for Auckland. We're certainly confident it'll generate more leads into Auckland's visitor market," he says.

Mr Warren says tourism is big business in Auckland, generating more than$3 million in GDP each year.
