Note: The ‘crude’ percentage is not adjusted for differences in the age structure of the Māori and non-Māori populations.

Around 1,780 Māori were estimated to have diabetes in 2013, giving a crude prevalence of 5% (not adjusted for age). Half of Māori aged 25 years and over with diabetes (48%) were regularly receiving metformin or insulin. Most (86%) were having regular monitoring of blood glucose levels and two-thirds (68%) were being screened for renal disease.

Note Ratios in bold show that Māori rates were significantly different from non-Māori rates in the DHB.

On average five Māori per year with diabetes had lower limbs amputated, at a rate 2.2 times that of non-Māori.
