To give you an idea, A cup of good coffee costs NZD4-5, a sandwich costs NZD4-5, a light lunch at café or fast food restaurant (eg. KFC, MacDonald, Burger King, Subway, etc.) costs around NZD10, a humble dinner at a small restaurant could cost NZD15-30 per person, but a nice 5 course dinner at a fine dining restaurant could cost NZD80 per person without counting in the drinks. http://www.nz-tourism.com/
