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. 

Renowned ornithologist and Dominion Museum head Robert Falla goes into the field to present this first edition of National Film Unit’s Land of Birds. His subject is the kōtuku or white heron, nesting in swamp forest by Ōkārito Lagoon, Westland — the only New Zealand breeding colony. In Māori lore the heron is the sacred 'He kotuku rerenga tahi' or 'bird of single flight', owing to its rare sightings. Grant Foster’s beautifully shot survey of the kōtuku’s Ōkārito summer housing screened on TV in 1972, and won a 1973 Feltex Award for Best Natural History Programme.

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.

This short National Film Unit documentary travels to Westland to meet the kōtuku or white heron. In Aotearoa, the kōtuku is known for its beauty and scarcity (the bird’s only NZ breeding colony is near Okarito Lagoon). The black and white film joins the ranger to go whitebaiting, as kōtuku arrive in spring. Kōtuku’s special place in Māori mythology is recounted, and legendary ornithologist Robert Falla checks out chicks in a crowded ponga fern nest. Directed by John Feeney, the film premiered in Christchurch in front of Queen Elizabeth, on her Coronation Tour.
