''It's our responsibility to provide that.
''We respect their right to protest but I would hope they respect our right to hold a conference and have our conference safe and secure.''
Greenpeace's senior climate campaigner Simon Boxer said today's protest was the first time in New Zealand that Greenpeace has invited the general public to take civil disobedience action en masse.
New York City rapper Action Bronson, who performed at Auckland City Limits on Saturday, joined the protest at Sky City.
One Auckland man blocked from getting into Sky City said it was a "pain in the arse."
The man who requested anonymity said he was due to meet potential investors in this country from Australia.
"I'm out here and they're in there," he said.
Protest leader Steve Abel said he apologised to members of the public affected but not the oil industry representatives at the conference.
