Prime Minister John Key says he is confident safety and environment rules being brought in to cover oil and gas exploration will keep out "cowboy "operators.
Speaking at an industry conference this morning Key said the country needed royalties from the sector to help maintain New Zealand's desire to spend like other first world countries.
In response to concerns about the danger of offshore drilling in particular, new health and safety and a new environment management regime are being brought in this year.
The industry still faced pressure from environmental groups.
"Some would go as far as halting exploration entirely. We believe if we don't know what's there how can we make informed decisions about managing resources for future generations."
