I'm trying to plan a trip to the North Island between Xmas and New Year. I'm planning to fly to Auckland, then hire a car and maybe visit Rotorua, Taupo, and also take in the Coromandel peninsula (Whitianga region). However I'm a bit worried that it will be really busy in these places around this time. We're interested in visiting some thermal pools/spas, seeing some great scenery, doing some quiet walks and generally having a peaceful, relaxing time.
Does anyone have any suggestions?
