After completing an M.A. in Art History in 1978 Alexa spent 19 years as a curator at Auckland Art Gallery Toi o Tamaki. She is now an independent writer and curator and in 2002 was curator of the exhibition Sir Edmund Hillary: Everest and Beyond for Auckland War Memorial Museum.
Her authorised, illustrated biography Sir Edmund Hillary: An Extraordinary Life was published by Penguin in 2005.
Alexa has written three books paying tribute to the skills of earlier generations of home cooks: Ladies, a Plate, A Second Helping and What’s for Pudding? A fourth book in the series, Ladies, a Plate: Jams and Preserves will be published this year. Alexa makes and tests all the recipes for her cook books – and takes all the photographs – in her home kitchen in Auckland.
