The Police Association is pouring cold water on a plan to use police officers to man airport security in a bid to reduce disruptions for travellers from planned strike action by security staff.
Aviation Security staff are proposing to run a series of three-hour strikes at Auckland Airport and Wellington Airport during the upcoming July school holiday period.
The Prime Minister John Key says Cabinet was briefed on the matter yesterday and says customs staff or police could "potentially" fill the void at airports.
Police Association president Greg O'Connor says the idea is ludicrous.
He said it would raise the prospect of police maintaining order at a picket line while other officers carried out the jobs of those protesting.
"It couldn't happen. It would be a conflict of roles. That's without even looking at the legality of it," Mr O'Connor says.
The Public Service Association and E Tu have agreed to attend mediation proposed by the Ministry of Business, Innovation and Employment, but both unions say strike notices for the industrial action will remain in place.
"We're hopeful Aviation Security Services will be able to bring an offer to the table which will resolve this stalemate," says PSA National Secretary Glenn Barclay.
Transport Minister Simon Bridges says the issue is a matter for the CAA to deal with as they see fit.
He says there has been a strong pay offer by the CAA and when compared across the public sector it is at the upper end of what has been seen.
Labour Leader Andrew Little, however, says security staff are under increasing pressures and are looking for reasonable pay increases.
He says it's up to the government to sit down and sort the matter out.
When asked today about the Government not ruling out bringing in police to cover the strike, Mr Little described such as move as "good old fashioned National union bashing".
