Until the amendment, the rules were standard, though the exemptions were convoluted.
There were three and a half days a year when almost all shops must be closed under the Shop Trading Hours Act 1990. Christmas Day, Good Friday, Easter Sunday and Anzac Day (until 1pm).
The "almost" all was where convolutions nestled. The exemptions were many and varied - convenience stores, service stations, pharmacies, souvenir shops had exemptions. Garden centres could open on Easter Sunday but not Good Friday.
Each year, busloads of tourists and caravanning families rolled into centres to find they could buy an apple tree but not a bag of apples; a postcard but not a stamp; a roll of dog food but not a raw Wagyu steak.
If anything, this Easter Sunday has the potential for greater bewilderment.
If you will, enjoy a stroll around the shops in Rotorua. Even go in and buy things. Drive just under an hour to Tauranga and you'll find the place closed.
As of yesterday, 15 territorial local authorities had adopted Easter Sunday policies. That's about 20 per cent of the 67 TLAs.
Some, such as Auckland, Tauranga and Whangarei, have already indicated they may ease open the doors next year.
One could hope for it all to shake down eventually to a standard policy throughout the country. That may also be a forlorn hope. Councils must review any local policies created for Easter Sunday shop trading no later than five years after adoption.
What cannot be ignored is the historical significance of the day. The number who believe the date holds religious sanctity has decreased, but the devotion of those remaining has not.
