Four long time friends, all of us senior citizens, walked for ten minutes from the cruise terminal to stop number 1 to catch the first bus of the day leaving at 9 a.m. We arrived at about twenty past eight and booked tickets on the website on our mobiles which cost us one hundred New Zealand dollars for two adults. We soon received emails with QR codes, then shortly after a member of staff arrived to scan the codes and issue tickets. The bus arrived and set off bang on nine. The first bus of the day was an open decked double decker, but we had various different types of buses as we got off and on during the day. One thing we were left wondering about was the supply of earphones, but they are not needed as the commentary comes out of speakers and was only in English. The service wasn't bad at all, and we did not have long to wait for another bus when we got off to explore. We really do think we got good value for money and would use this service again.
