"The dunes behind the shoreline will continue to grow because it's a natural process. But the aim is to maintain a clear beach for both swimmers and other beach users.
"During a windy summer, such as we're experiencing, the sand builds up and we have to remove it," he said.
A review of beachfront maintenance was scheduled for 2015-16 and the issue would probably focus on whether people wanted a clear beachfront or a more natural one, with dunes and access via timber walkways.
"We certainly need some expert advice on how we could handle it," Mr McGregor said.
Mayor Annette Main said council had been approached by people "representing both sides of the argument".
"The least we should be doing is meeting with the people most interested in the beachfront," Ms Main said.
"It's not about having a fight over this but rather find out these views and look for solutions, because it's going to come up constantly."
Mr McGregor said council had tried to encourage Horizons Regional Council and the Department of Conservation to be involved but he said while they were sympathetic they were not signalling any financial support.
