"What might be appropriate and relative for Tauranga might not be for the rest of New Zealand," Mr Crosby said.
"To put it in context, over Easter we are an events and tourism destination. The city is vibrant with lots of people here. My personal view is for trading on Easter Sunday in Tauranga, if people choose to."
Mr Crosby said the council would be required to draft up a proposal, seek consultation and feedback and, ultimately, make a decision.
There would be little cost associated with the council taking on the legislation, so long as it was made clear, simple and understandable from the beginning, he said.
"My view is it's either all in or all out. At the moment garden centres can open so long as they sell a plant. The more complex you make it, the more expensive it's going to be."
However, Western Bay of Plenty Mayor Ross Paterson disapproved of localising the legislation to a district level.
Mr Paterson said he personally had no qualms with shops opening on Easter Sunday however, the move would result in different bylaws for different districts, creating confusion among shoppers and visitors.
"You will go to town and you won't know if the shops are open for Easter trading until you get there. There will be nothing standardised throughout the country," Mr Paterson said.
In Rotorua, Mayor Steve Chadwick was all for opening shops on Easter Sunday.
