Judy Corbalis was born and grew up in New Zealand but now lives in London. A former Hawthornden Fellow and Visiting Scholar at the Centre for Women Leaders at Lucy Cavendish College, Cambridge, she has an MA in Creative Writing from the University of East Anglia and was the inaugural Royal Literary Fund Fellow at the Courtauld Institute of Art where she currently holds the post of Academic Support Tutor.

She has adapted her own work for radio and has written and fronted television programmes for children. Her children's books have been published by Deutsch, Hodder and Scholastic — children love them for their humour and the fact that no character behaves as expected. Her new children's book, Get That Ball, illustrated by Korky Paul, was published by Andersen Press in May 2018. Her adult novels include Tapu, and Mortmain, shortlisted for the 2009 Encore Award.

She is married to the sculptor Phillip King, PPRA, and makes frequent visits to New Zealand.
