Most families living in one household try to eat dinner together several times a week. The formality and structure of these meals vary from family to family. Although few New Zealanders cook most things 'from scratch', most New Zealand home cooks are dependent to some extent on pre-made ingredients (in particular, packaged soup and sauce mixes). Cakes are very rarely made from packet mix - this has never really taken on in New Zealand. Most families eat takeaways (take-out), such as fast food, fish and chips, Chinese food, or pizza about once or twice a week. In flats (households shared by a group of unrelated young people), flatmates will generally either take turns cooking or each cook and eat individually.
