I've finally been able to read this, as I recently moved to Dunedin for work and there's a copy in the Hocken Library. It has to be read in the library, but that's alright as it's less than sixty pages long.

Acres was a writer and artist of children's books in New Zealand. She's mostly known now for her Hutu and Kawa picture books, first published back in the 1950s, which used flower fairies to talk about native plants and animals. I'm currently working on a project which includes a short study of these books, so I wanted to read a biography of Acres - and this is it, there's vanishingly little else - to see if there was any useful information that I could reference. There is, so that's helpful! Otherwise, it's a short chatty bio, and if it doesn't go into very great depths, it's still readable and interesting.
