Thirty per cent of the New Zealand population rated their trust in Parliament as high, and a further 9 per cent rated their trust very high, according to Statistics New Zealand.
But almost half of Māori (48 per cent) said they had low trust in Parliament.
On the other hand, 29 per cent of people in New Zealand rated their trust in Parliament as low, according to answers to the 2016 New Zealand General Social Survey's questions on political participation.
The two-yearly survey asks about 8,000 people a range of questions, including on voting, political discussion, signing petitions, as well as perceptions of trust and political influence.
