Her PhD, official on May 3, was from the Edith Cowan in Perth, Western Australia.
"There wasn't a university in New Zealand that could allow me to do a PHD in writing, unfortunately," Ms Fiske Wake said.
Inspired by E Nesbit's The Story of the Amulet, her thesis novel was about time travellers and was aimed at young adults.
In an earlier interview, Ms Fiske Wake had explained how she had had to write a novel of literary quality as part of her PhD thesis.
She has written and had published two Gothic novels.
Now in her 70s, she said the way ahead was filled with project ideas.
"I'm tossing up between an adult novel and a screenplay ..." Ms Fiske Wake said.
