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.
BE CAREFUL AND KEEP SAFE
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.
Tread carefully. Leave creatures where you found them. Leave attached seaweed in place. Handle creatures with care - close to the
ground with wet hands. 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.
This guide illustrates only some of the more common seashore animals and plants. Visit our website for a comprehensive list, Māori names and information about their ecology.
