Dr John Dawson, 1928-2019, was Associate Professor of Botany at Victoria University. He published many books, but 'New Zealand's Native Trees', and the companion field guide are arguably his greatest legacy. Dr Barry Sneddon lectured for many years at Victoria University, and was a close colleague of John Dawson's. He has been responsible for all of the amendments in this revised edition. Rob Lucas lectured at the Open Polytechnic in Lower Hutt until his retirement and has been photographing native plants for many years.
