A good variety store is the place to find a bit of everything in one stop, such as household goods, stationery, party supplies, toys, cleaning products and small gifts. Stock changes often, so a quick look around can turn up bargains and useful extras, but it is worth checking labels, age warnings and quality on electrical and children's items. Ask staff if you cannot find something, since variety stores often keep lines in less obvious places. Regulars drop in before birthdays and school terms to stock up on small items, and they visit early in the day for the best choice.
For people in Golden Bay and Nelson, Dollarama is worth contacting or checking online for what is in stock and when it opens.
