"A lot of people didn't agree in principle, but people and retailers have adjusted."
Being a tourist destination, Byrne believed it was important for shops to be open on the holiday.
Be Rude Not To cafe owner Priscilla Reid said the cafe would definitely be open.
"It's a time for families to get together and come out for breakfast."
She was hopeful that town would be busy.
The cafe would also not have a surcharge on the public holiday, she said.
Rotorua Stirling Sports manager Dean Katipa said the store would be open again on Sunday.
The day was "a little bit quiet" last year, but he believed that would change if more stores were open.

Rotorua Chamber of Commerce chief executive Allison Lawton said the chamber supported any initiatives that enabled businesses to grow.

There will be plenty of people around to take advantage of the open shops over the weekend, with several big events in Rotorua.

Rotorua i-Site senior travel consultant Sabrina Gogg said there had been "lots and lots of inquiries" from people about accommodation in Rotorua over Easter.

A "huge" number of people travelled to Rotorua for the Easter break last year, and she thought that would be the case again this year.
