There was no public tender, council deciding on its preferred option after speaking to a range of security firms about options for the gate.
"This is an interim arrangement, as it was important that we had a robust structure in place for the busy holiday period," Mr Evans said.
The only landowner adjacent to the car park, Andy Lowe, has voiced his opposition to the gates.
In a letter to the editor published in Hawke's Bay Today he said a member of his staff had been approached by council to open and shut the gates.
Mt Lowe said the action was unwarranted and is concerned campers on his land enjoying a "traditional summer holiday camping at the beach" would now be impeded.
"It is concerning to me that the council should, in publicly announcing its decision, imply that I have agreed to it, possibly to divert any negative reaction to the news away from it," he said.
The surf club's chairman, Richard Wilson, said he was unaware of any incidents of vandalism at the beach.
The surf club operates on land owned by the council.
