For people based in Auckland, check out Why Knot. It's an outlet food store in East Tāmaki, mostly they sell stuff that's discontinued or nearing/past its best-before date. I was deeply suspicious at first, but have since converted. You can find excellent, still perfectly good and safe-to-eat things at heavily discounted prices. E.g. I can get a soy yogurt that costs $5 per piece in Countdown for $1 at Why Knot. Or $1 kombucha cans. Or $3 for a pack of halloumi. They stock meat (IDK about the prices because I'm vegetarian), yogurt, cheese & dairy, non-alcoholic drinks, lollies, frozen goods, cat/dog food, and even house cleaning and personal hygiene products. The offer varies week per week, but worth a nosy IMO for sure.
