Parts of Waiheke are quite hilly, so ease the load with a hybrid machine from Onya Bikes, combining pedalling with electric motors.
The island has bus services, starting from Matiatia Wharf and heading through Oneroa (adult/child $2/1, three minutes) on their way to all the main settlements, as far west as Onetangi (adult/child $5.50/3, 35 minutes). A day pass (adult/child $10/6) is available from the Fullers counter at Matiatia Wharf. Some services in the middle of the day can be as much as an hour apart, so to avoid lengthy waits at bus stops, consult a timetable from Auckland Transport.
Another option is the Waiheke Island Explorer bus, a hop-on, hop-off service covering 15 different stops around the island. A full circuit takes 90 minutes and attractions along the route include vineyards, beaches, activities and restaurants.
