Jetboating , another New Zealand invention, consists of high-speed boat trips in special power boats. It is available to people of all ages and popular on many of the country's best known rivers. Surf rafting invites visitors to accompany experienced rafters through crashing waves while simultaneously being offered a commentary on the coastline nearby. Zorbing involves being strapped into an inflatable transparent plastic ball, which is then rolled down a grassy hill or onto a river. Divers need to bring their diver's certification cards.
Many dive stores offer equipment rental and support facilities.
