They have friendly staff and you can use the AA traveller voucher to get the price down to 245NZD for a 40min flight. The pilot had good routine and found the sperm whale quick after 8min and we spend 8min to fly around the whale BUT honestly the whale seems tiny and could be a submarine, too. You don't get a feeling for its size. We found another whale then and after it dived we flow back. Just 33min flight although 40min paid :( could have spend the time remaining to find a pod of dolphins for example.
