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

Half of Māori children aged five years in 2012 had caries, 35% higher than the proportion of non-Māori children. The mean number of decayed, missing or filled teeth was 1.9 for Māori compared to 1.6 for non-Māori.

Of those in Year 8 at school (aged around 12 years) half of Māori had caries, a fifth higher than the non-Māori proportion. The mean number of decayed, missing or filled teeth was 1.3 for Māori and 1.0 for non-Māori.
