Award-winner Hidden Places: Ōkārito marked an early milestone for the Natural History Unit (later to become NHNZ) — it was part of the first series made by the unit. The 15 minute episode follows birds, such as white heron, Russian godwits and royal spoonbills, all of them flocking to Ōkārito's "unique world of sea, lagoon, rivers and forests". Logging of kahikatea, the tallest endemic forest tree, also features. Robin Scholes, later to produce movie Once Were Warriors, wrote and directed this episode. It won Best Documentary at the 1979 Feltex Television Awards.
Winter is going. This impressionistic take on spring in Aotearoa focuses on details of regeneration, from the mountains to the sea. Director Ron Bowie and cameraman Grant Foster capture signs of the season: ice melt like tadpoles under snow grass, gannets nesting on their Cape Kidnappers tenement, fern koru unfurling, kōtuku and royal spoonbills perched in Ōkārito trees like Dr Suess characters, willow buds and kōwhai flowers. And of course, lambs and daffodils. The camera aptly obeys the title to end. Patrick Flynn (Don’t Let it Get You) composed the score.
