"Our goal is to operate without any risk to people and the environment. If there is a risk we will stop operating," he said.
He conceded that "small leaks" had occurred in Statoil oil drill areas.
"This is public information," he said.
"We are aware that there are risks. We are very proud of mitigating the risks, and there has been no permanent damage to nature anywhere. We realise a big blow-out here would have a catastrophic effect, so that is not an option. We will not take any risks to cause oil pollution.
"If there is an accident we will take responsibility. We will be here to clean up if there is a spill.
"The reason we are here is honestly because your government has invited us to do this. We haven't taken any decision to drill yet. That will come in six years' time, if at all.
"For us this is early days. I will remember all you say today and take it with us into the future. We are very committed to an open discussion with iwi, without conditions. I can promise that we will try and be a partner in the future."
The only remotely positive response, however, was that "If we are going to dine with the devil, we may as well choose the best devil there is."
