Treasure Island was an early local example of a reality show staple — contestants endured the great outdoors, and each other. Over nine seasons the series went through multiple variations, including a Couples at War season, and another featuring favourites from the past. During the 2004 season of Celebrity Treasure Island, contestant Lana Coc-Kroft was airlifted from Fiji, after she cut her foot on coral and got a life-threatening blood-poisoning disease. On 2002's Treasure Island: Extreme, Barrie Rice — an ex SAS soldier — dealt with being eliminated by hiding in the jungle.
Hosted by Charlotte Dawson, How's Life? was an advice show whose panel of presenters included Jude Dobson, Suzanne Paul, Paul Henry, Marcus Lush and Christine Rankin (ex head of the Department of Work and Income). Responding to viewer enquiries, the panel offered help on relationships, family and more, from the serious (abuse, disease) to the light-hearted (the best way to sneeze in a restaurant). Almost 20 panelists featured over the Greenstone show's three seasons and 100+ episodes. The production crew received as many as 60 letters and emails a day.
