However, he was pleased he had been at the meeting rather than hearing about it from Oslo, given that he had learned that he would have to talk to all iwi, at hapu level, and was more convinced than before that communicating with local people would be the key to the company's success.
The strength of opposition to seismic testing had also come as a surprise, because oil drilling had previously been the main concern of iwi. In 40 years of exploring Statoil had not recorded any permanent damage to marine mammals caused by seismic testing.
The hui had also taught him that the company had not communicated as well as it could have about the potential benefits of oil exploration. However, at this early stage the company could not promise thousands of jobs.
"It's a long-term thing. We don't want to go in with big words and big promises," Mr Haremo said.
"As long as we feel we can have constructive meetings, and we are safe, we will continue to try to consult," he added.
"I think we have a very good case to explain that it's sustainable. I come from a county that has beautiful nature, beaches and marine mammals as well, so I can understand (public concerns), but I'm a little confused about not letting information flow."
Claims that seismic testing does no lasting damage are disputed by Greenpeace and Otago University associate zoology professor Liz Slooten, who said it could lead to more whale strandings and leave some species of whales and dolphins effectively deaf and blind.
