Saving New Zealand’s Heritage Food Plants

Kōanga’s story begins in the early 1980s when founders Kay Baxter and Bob Corker moved from Auckland up to Bob’s family farm in Kaiwaka. Kay noticed that the wild fruit trees growing along the roadsides and around the Kaipara Harbour were healthier and more productive, with far better tasting fruit than anything available in the Garden Centres. Kay realised that these trees had been brought here by early settlers and that they were mostly neglected and dying out. This prompted her to start collecting these heritage fruit trees, and in the process also began to collect and realise the importance of their stories and their whakapapa.
