Statistics from the Ministry of Health show more than 200,000 people in New Zealand have been diagnosed with the disease. The majority have type 2 diabetes and the prevalence of diabetes in Māori and Pasifika is about three times higher than other Kiwis.

The book will be launched at the Giraffe Restaurant, in Auckland, tomorrow. It coincides with Diabetes Action Month this month, which is promoting the theme: Act now to live well.
Giraffe is owned by Kiwi celebrity chef Simon Gault, who also has diabetes.
"As a chef and having battled type 2 diabetes myself, I'm all too familiar with how smart and inventive you have to be to put healthy food on the table."
Recipes in the book include vegetarian options, mains, salads and desserts; and also has healthy versions of traditional Indian, Sri Lankan, Thai and Pasifika dishes such as povi māsima (corned beef) and sapasui (chop suey).
There is a take on the classic boil-up and parents who have children with diabetes will find snack and lunchbox ideas too.
All the profits from the book will go to supporting Diabetes NZ's work.
