Early stages of planning a trip to NZ to see my dad and his family on South Island. Will be me and dh with kids who are 6 & 9yo currently. Thinking to go this time next year, or the one after. Where could we stop to break up the trip? The ideal would be a couple of day lay up where the airport is convenient to see some sights. I would love the kids to experience a different culture. Even better if it helps with jet lag and flight prices, not sure if that's possible!
