This TVNZ kidult drama is a saltwater Swallows and Amazons, where the plucky "urchins" stumble upon villainous plots (from missing treasure to wildlife smuggling) on their seaside adventures. Over three series, locations like Mahurangi Peninsula in the Hauraki Gulf — where the youngsters holidayed with their uncle — and the Marlborough Sounds allowed for much floatplane, launch and navy frigate chase action. The cast included an array of experienced talent and featured a young Rebecca Gibney (the Packed to Rafter’s star’s first major TV role) and Robert Rakete.
For the third series of this TVNZ kidult drama, the location moved from the Hauraki Gulf to the Marlborough Sounds, where there's also plenty of water for floatplane and speedboat thrills (and an explosion). Brothers Peter, Nik and Hape — the "sea urchins" — attempt to foil a thuggish gang of tuatara and kākāriki smugglers, led by cravat-wearing evil mastermind, Carl. The urchins are aided on the ground and in the air by a young Rebecca Gibney (the Packed to the Rafter's star's first major TV role), while future broadcaster and Wiggle Robert Rakete plays Nik.
