Supermarkets were not the only stores benefiting from the wild weather.
Mitre 10 Mega general manager for Napier and Hastings Rodger van der Gulik said a lot of customers had been purchasing camping equipment as well as kindling, firewood, and heaters.
A few camping equipment supplies, such as certain torches and batteries, had sold out, and kindling had "gone like mad".
Mr van der Gulik said there had been a good number of customers to both stores - they had systems in place, such as emergency power generators, so they could keep operating while supermarkets and the Warehouse could not.
