KEY POINTS:
Wellington City Council has given the National Party surveillance camera footage which might help it identify the infiltrator who secretly taped conversations with MPs at a cocktail party on August 1.
There were no cameras inside the room where the party was held but there was cover of a staircase leading to it, said council spokesman Richard MacLean.
A young man wired for sound got into the cocktail party, held on the first night of National's annual conference, and goaded senior MPs into talking about sensitive policies.
Posing as a member of the party's youth wing, he recorded deputy leader Bill English saying National would "eventually" sell Kiwibank.
Another senior MP, Lockwood Smith, talked about "swallowing dead fish" to keep the public happy with policies National didn't agree with ahead of the election.
The comments laid National open to a torrent of criticism from the Government and ministers claimed they were evidence of a secret agenda.
"The reality is the footage isn't that great," a spokesman for party leader John Key said.
"Whether we come up with something is anyone's guess. It's not going to be a quick process."
