"That doesn't surprise me," he said. "But there's no question we should work harder to persuade a higher number of Kiwis about the strong rationale for what we are doing. Here is one of the arrows in our economic quiver."
Green MP Gareth Hughes said the increase in opposition was because Anadarko had started work on exploratory drilling, making it a reality and boosting nervousness about an oil spill.
"We've seen Anadarko arrive ... and Kiwis know the risk of oil washing up on our beaches is real. The process is a mess and the oil spill response plans are a joke."
Labour's economic development spokesman Shane Jones said the increase in opposition showed the Government and Mr Bridges were failing to properly counter a "sophisticated anti-campaign".
"Politics, unfortunately, is as much about heat as it is about light. There is no light emanating from the Government, but there is considerable heat being generated by New Zealand. If that is allowed to drift, the largely ill-informed public can be swayed by fear mongering."
Mr Bridges said a comprehensive range of checks and balances had been set up. The Government was ensuring responsibility for any spills was on the company involved.
"We are very clear there needs to be the highest health and safety and environmental practice. There's no room for cowboys."
He was satisfied with Anadarko's plans, as well as the capacity of Maritime NZ in dealing with an emergency if there was a delay in Anadarko implementing its response.
Since the Rena grounding off Tauranga in October 11, there had been significant investment in resourcing and training for Maritime NZ.
Anadarko's exploratory drilling off the Raglan coast began in November, prompting protests including a flotilla and Oil Free Seas protests at beaches such as Raglan and Piha.
Greenpeace has also begun legal action against the Environmental Protection Agency and Anadarko over whether the company should be allowed to drill in the Taranaki Basin.
