It's estimated up to 75 per cent of its staff are members of the E tu and Public Service Association (PSA) unions.
E tu Aviation spokesman Kelvin Ellis said the workers didn't want to take the industrial action, the first in 30 years, but felt they had no other option after almost a year of negotiations.
"They've reached absolute frustration ... they don't want to but they don't think they have any other choice. They've had enough."
Mr Ellis said the strikes would likely have a "significant impact" on screening times and would impact flights being on time, but he didn't think it would result in cancellations.
National secretary for the PSA, Glenn Barclay, said their members were reluctant to carry out the industrial action but felt they had no choice because the latest offer meant some would go three years without a pay rise.
Mr Barclay said it was clear the service has the money to make a better offer, since its annual report showed a surplus of $5.8 million in 2014-15.
"Aviation security workers are law enforcement officers, who help make New Zealand's aviation industry one of the safest and most highly regarded in the world."
The strikes could be prevented by the service making its staff a "fair offer" which addresses their concerns and ensures they are fairly rewarded for the crucial job they do, Mr Barclay said.
Civil Aviation Authority spokesman Mike Richards said airport security would not be compromised by the strikes and there are contingency plans in place. He hoped the issues could be resolved amicably.
