Four of us will be flying from the US into Christchurch for a self tour of South Island before leaving for a 16 day cruise out of Auckland a week later. Is there any place to store our larger cruise-wear packed suitcases so we can take only 3 or 4 carry-on size suitcases in the rental car?? We were not staying overnight in Christchurch at the end of tour, so not sure a hotel would keep our luggage since we are not returning to stay in the hotel,
Also, will it be difficult to fly from Christchurch to Auckland with a carry-on size + full sized suitcase each??
