Prime Minister John Key says a group of angry protesters did not ruin the National Party's Christmas function as they banged on the windows amid a heavy police presence last night.
About 30 members of the Auckland Action Against Poverty (AAAP) group occupied the second-storey balcony of the Auckland Grammar Old Boys' pavilion, peering in at Mr Key and other party-goers.
Another group of about 30 formed a picket line at the entry gate on Mountain Rd in Epsom.
Mr Key told Newstalk ZB this morning that the protesters had not ruined the party.
"They're the same people protesting about deep sea oil drilling, they're the same people protesting about the convention centre, they're the same people that protested about changes to the labour laws for the Hobbit, they're the same people that protested about the 90 day probationary period.
