A survey conducted by Te Tai Tokerau MP Kelvin Davis which showed overwhelming Maori opposition to deep sea oil drilling was conducted after he struggled to gauge where Northland Maori stood on the issue.
Mr Davis sent out a survey with Christmas cards last November to all 32,000 people in the Te Tai Tokerau electorate asking what they thought about deep sea oil drilling.
Of the 32,000 people who were sent the survey 6032, or 18.3 per cent, responded by mid-January - 5199 saying they opposed deep sea oil drilling, 236 supporting it and 531 who said they needed more information on the topic before making a decision.
Norwegian company Statoil has been granted two licences to explore for oil in the Te Reinga Basin but no drilling has taken place yet.
"One reason I did the survey was because I didn't know where people in my electorate stood. A lot would turn up to hui and be angry and shout and others would say they wanted to have their say but they were kind of shouted down by others," Mr Davis said.
