Mr Walford said locking doors over Easter frustrated many Kiwis who hoped to use the long weekend productively.
"We have a culture in New Zealand of DIY, and for a lot of people the only chance you get to do those bigger projects is on long weekends."
Mitre 10 Mega Napier and Hastings have broken trading laws and opened for business on Easter Sunday for the past 10 years. Managing director Graeme Ricketts said he had been fined in the past but that had never been a problem.
"I would say the public expect stores to be open on Easter Sunday in this day and age," he said. "The trading we're doing on Easter Sunday indicates there's certainly a demand there."
Mr Ricketts said allowing stores to open "needs to be a central government decision". He said he had no problem closing his doors on Good Friday.
Nationwide, there were 15 Easter trading complaints - well down on the 42 lodged last year, and the lowest in at least four years.
Retail New Zealand spokesman Greg Harford said the Easter trading laws were "completely archaic".
"We're really supportive of moves to liberalise trading over Easter. We have got some concerns about the specific legislation the Government has in the House, mainly around the bylaw giving power to local authorities."
Mr Harford said the Government should have taken the opportunity to present a bill changing the law nationwide. "It doesn't make sense. It's going to be confusing and it's really expensive to administer bylaws."
However, it was a step in the right direction and there was widespread support for a change in the law.
The bill - expected to be in place by next Easter - would allow any employee to refuse to work on Easter Sunday "without giving a reason".
