In New Zealand, it is estimated that the number of people diagnosed with diabetes exceeds 200,000 people (predominantly type 2 diabetes). There are also about 100,000 people who have diabetes but have not yet had it diagnosed.
Within the New Zealand population, the prevalence of diabetes in Māori and Pacific populations is around three times higher than among other New Zealanders. Prevalence is also high among South Asian populations.
Although type 2 diabetes is increasingly being diagnosed in children and is related to obesity, type 1 is also increasing. Good control of blood glucose in early life appears to be beneficial and people with better diabetes control have fewer complications.
