Dolphin rules:
• A maximum of three vessels (including jet skis and kayaks) are allowed within 300m of a group of dolphins.
• Keep your speed to a minimum - no wake allowed within 300m.
• Approach dolphins slowly, from behind and to the side of the group.
• Never drive through, cut off or circle a group of dolphins.
• Don't make sudden or repeated changes in direction or speed.
• Don't attempt to swim with groups with calves or juveniles (animals less than two-thirds the length of the adults).
• Keep noise to a minimum. No boats are allowed within 50m of whales or 200m of female whales with calves.
• If you notice a marine mammal being harassed, severely injured or entangled, or in the event of any other conservation emergencies, phone 0800 DOC HOT (0800 362 468).
