This wee gem from the 60s Sunday night magazine show records a pivotal New Zealand conservation moment. Wildlife Service ranger Don Merton experiments with rescue techniques to save the endangered North Island saddleback (tieke), a wattlebird surviving on Hen Island. Aided by electronics expert John Kendrick (of National Radio bird call fame) he uses calls to lure the spry birds into mist nets before moving the precious cargo to cat-free Cuvier Island. The world-leading skills developed here were to be crucial in saving the black robin and kakapo from extinction.

This Wild South edition joins two legendary New Zealand wildlife documentarians — photographer Geoff Moon and sound recordist John Kendrick — on a 1988 trip to Kāpiti Island. Rangers are learning about, and looking after, the sanctuary’s manu (birds), who are “biological refugees” from the mainland, escaping introduced predators. Dogs monitoring kiwi, a kākā census, and tīeke (saddleback) nest boxes are featured. The two old mates narrate the visit, which includes Moon building a bush hide, and footage of a pioneering 1964 tīeke relocation from Hen Island.
