If you're in a aquatic frame of mind, check out these great on-water excursions.
1. Puhoi River
Kayaking from the historic village of Puhoi all the way to Wenderholm Regional Park is an easy 8km of water, timed so you've always got the incoming and outgoing tides pushing you along, and there are no rapids or waterfalls. Helpful maps and training for beginners before you set off, with pretty native bush, farms and mangroves to admire.
2. Waikato luxury
Take an experienced skipper (even catering and staff if you wish), join the Riverlands Discovery luxury houseboat, a Murray River-type experience running from Tuakau to the serene northern stretches of the Waikato. For the best of both worlds, jump off for a quiet kayak paddle, then head back to the houseboat pampering.
