Heartland host Gary McCormick visits 'New Zealand's last frontier' - Haast on the West Coast. It's whitebait season, and Haast's population has increased five-fold. McCormick talks to whitebaiters on the Arawata River and a Department of Conservation Ranger, visits a "secret whitebaiters' town" and helps local residents prepare for the annual Whitebaiters Ball. When McCormick asks what the best line for getting a girl to dance is, one of the locals tells him to say, "I've got a Valiant". The programme also touches on the tensions between some residents and conservationists.
