I stayed in North south holiday park on the day of arrival and the night pre departure from Christchurch. It is located about 5 mins drive or 45 mins walk from CHC international airport. You can book their airport shuttle ($5 per pax) during operational hours or the front desk can order a taxi for you at a cheaper price. Amenities are complete and cleanliness is well maintained. The only set back is there is no eateries within short walking distance except burgerking, but not a problem if you come with a car or you can cook at their kitchen(with utensils provided)
