Social media reaction to the store being open has been a mixture of comedic repartee and disbelief.
"That's far from essential," wrote several people on a local Facebook thread about the store's opening, while another said the owner had obviously made a mistake.
But others disagreed in a tongue-in-cheek way, saying "It's an essexual business" and argued the store was important "for the girls".
Adult Selections is outside the membership zone for the Hastings City Business Association, however the association's marketing manager, Emma Sey had some advice for the owner.
"If any businesses are unaware whether or not they are an essential service, they should visit the Covid-19 website.
"There is a webpage specifically around doing business at level 4, so I would recommend that if people are unsure they should visit the Government website and check Government guidelines about doing business at alert level 4."
There's potentially a good business case for staying open - the last lockdown started a boom in the sales of adult toys in the region.
Just down the road, Havelock North topped a NZ-wide spike in sex toy deliveries, with sales growth of 401 per cent from May 2019 to May 2021, according to data released to Hawke's Bay Today by Adulttoymegastore earlier this year.
