On my go-to kai Māori books, the end of Karen's Diner and a snack evoking the sea.
I was learning te reo in the 1980s(*) I had a copy of The Maori Cookbook, just like the one in the picture. So I would put the date back from 1996 to 1985 -- possibly earlier. The one in your photo is spiral bound, but my copy was folded and stapled, from memory. The style of typesetting and printing looks quite 1980s to me.
*I was learning te reo when I was a high school student, but not at school, since they only had French and German as language options; instead I went to a summer school in 1982, community college night classes (1982-83), and I also studied it through the (then-named) Correspondence School. Glad to see that my former High School in Otautahi now has its own marae! :-)
