We rented bikes in two locations on our December 9 Celebrity Edge...Napier and Dunedin. We used Napier Bike and tour and did the Waterways to Winery self tour (rental bike, helmet, map) and they pick you up at the Church Road Winery at a set time. It was across the street from where the bus drop you off from the port and they did a great job. For Dunedin, we used ihirebikedunedin.com or something like that. We met at their office/home in Dunedin or drop it off at the Library in Port Chambers (recommended). We did the loop with the port to port bike ferry and had an awesome day. The bike trails in New Zealand were absolutely beautiful.
