Those party discussions took place six weeks ago when the electorate team tossed around and threw out Mr Davis' call for public donations to help "take down Kim Dotcom and stop him from buying the seat of Te Tai Tokerau with his $3 million", he said. Mr Davis is taking on Mana Party leader Hone Harawira in the Te Tai Tokerau seat.
Labour's election game plan is "be positive" and its slogan is "vote positive" but Mr Davis denies party bosses have ticked him off for not playing nicely when he described, again via social media, the Internet Mana Party as "the biggest con in New Zealand's political history".
Meanwhile, Mr Harawira is also calling foul play - against Mr Davis.
"I was shocked, dismayed and hurt, to hear that Kelvin Davis was secretly canvassing for funds from National to campaign against me," Mr Harawira said.
"I am sad to hear that he refuses to acknowledge what he has done and refuses to apologise for his tactics.
"We may be on different parties, but our people want this to be a campaign of ideas and values, our people do not want this to be the dirty and underhand campaign that Kelvin has made it into."
Mr Harawira has called for an apology from Labour, but none will be forthcoming.
Mr Davis said many "ordinary New Zealanders" had contributed to what was as much an awareness raising campaign as a fundraiser and he had not asked for money from National Party supporters or other right wingers.
