Mr Davis said deep sea oil drilling had been a "hot topic" in Northland recently and as Te Tai Tokerau MP it was important for him to know the opinion of Northland Maori.
"I'm not the MP of any other electorate," he said.
"You take into account this information when you make decisions so when this issue is raised I can clearly say, without hesitation, this is Tai Tokerau's perspective."
Mr Davis acknowledged it was not a "scientific survey" but said he was surprised by the results.
"I thought it'd be a lot closer, I would have thought there would have been more of those in favour. To some extent we are a bit hypocritical because we all love our vehicles and everyone has a four-wheel-drive, we all drive down the beach and go fishing," he said.
"But what people are saying is we need to find a different form of fuel and the risk of an oil spill off Northland was enough to warrant a vote opposing deep sea oil drilling."
He said ultimately people wanted to ensure the resources available to them now, were available to future generations.
