Promising a new kind of environmental journalism, Cape Town-based conservation writer Adam Welz's book The End of Eden: Wild Nature in the Age of Climate Breakdown explores climate change from the perspective of wild species and natural ecosystems.

A collection of letters written to and from iconic New Zealand painter Colin McCahon sheds light on a special relationship spanning four decades. McCahon met penpal Ron O'Reilly in 1938, when the pair were just 19 and 24 respectively. They wrote to each other regularly, amassing hundreds of letters covering McCahon's art practice, the contemporary art scene, ideas, philosophy, and spiritual life. A selection of the letters chosen by McCahon scholar Peter Simpson has been published in a new book Dear Colin, Dear Ron - with an afterword by McCahon's grandson Finn.

Thirty years ago, nurse Maybelle Ngapere McLeod realised a genetic link to the stomach cancer which killed many of her whanau was much more likely that the effect of a curse. She took her suspicions to Otago university, and the rest is history. Maybelle is part of the team awarded the top Prime Minister's Science Prize for transformative impact. The Hereditary Diffuse Gastric Cancer Team is led by Professor Parry Guilford, Director of the Centre for Translational Cancer Research at the University of Otago, in conjunction with members of the McLeod whanau and their community in Mount Maunganui. The research has resulted in a genetic test which gives the ability to understand their risk of cancer and take life-saving action. Professor Guilford joins Susie, along with Mabelle Ngapere McLeod and fellow team member, and whanau University of Otago Associate Professor Karyn Paringatai.
