Show RESPECT FOR SEASHORE CREATURES

Tread carefully. Northern NZ Leave creatures where you found them. Leave attached seaweed in place. Handle creatures with care - close to the ground with wet hands. Sandy & Muddy Carefully put sediment and rocks back to the same location you found them. Limit your collection of empty shells as other creatures may use them as homes. Shore Guide

AVOID DISTURBING WILDLIFE Keep your distance from seabirds including penguins. Keep your distance from seals and sea lions. Use the zoom on your camera or binoculars for close viewing. If sea lions approach you - back away slowly. Keep dogs under control. Pick up any rubbish found.

Check tide times to avoid being cut off by rising tide. Do not explore the seashore alone. Watch for changing weather. Look out for waves - never turn your back to the ocean. Soft mud can be dangerous. If you start to sink turn back. Check signs for any local hazards.
