A National MP was allegedly the source of a tip to Len Brown's campaign team that the mayor's affair with Bevan Chuang was going to be made public.

A source inside the Brown camp told the Herald yesterday that the campaign team was alerted to the sex scandal about lunchtime on Monday, October 7 - five days before postal voting closed in the local body elections.

"We got told a National MP said to a councillor that there was going to be a major sex scandal in the media involving Len Brown," the source said.

Last night, Rodney councillor Penny Webster, a former Act MP and loyal supporter of Mr Brown, would neither confirm nor deny passing on the tip to the Brown campaign.


"I think it's immaterial. It's over. Len has talked to his wife and we're getting on with life," she said.

On the same day the Brown camp received the tip, right-wing blogger Cameron Slater wrote a post urging people to vote for John Palino and saying that Mr Brown likes to cast a "glad eye over Asian beauties".

After the tip-off was given, Mr Brown was told and left the Auckland Town Hall to go home to Manukau where he told wife Shan about the affair. He was later joined by his political adviser David Lewis.

That evening, Mr Brown cancelled a mayoral debate hosted by the Takapuna North Rotary Club at Spencer on Byron hotel in Takapuna, citing a bad cold.

It was a very tough week for the Brown campaign, the source said, not knowing when or if the affair would come to light.

But as about two-thirds of the votes had already been cast or were in the mail at the start of the final week of the postal ballot, the Brown camp did not believe the affair being made public would materially effect the result.

When Mr Slater did reveal the affair on his Whale Oil blog at 2pm on October 15 - three days after the election result - Mr Brown was at home, resting and recuperating from the campaign and a lingering cold.

Prime Minister John Key said on Monday the National Party was not involved in the scandal.

Luigi Wewege, 28, who belongs to the National Party youth wing and was a member of Mr Palino's mayoral campaign, was in a relationship with Ms Chuang and wanted her to expose the mayor's infidelity.

Mr Wewege has gone to ground since a Facebook message exchange he had with Ms Chuang was revealed by the Herald last week.
