Rockpools are an integral part of the New Zealand Seashore, this stamp booklet issue depicts this unique environment. When joined together, the stamps formed a continuous picture across all ten stamps of the booklet.
The seashore rock pool is a unique environment in which not all sea creatures can survive. At high tide, it is completely submerged under water, sometimes covered by up to a meter. As the tide goes out, the rock pool is swept with the waves of the falling tide before becoming completely isolated from the ocean. It is at this point that the water left in the pool can get heated by the hot summer sun, sometimes almost drying up the pool. Then in comes the ocean again, a period being swept by the waves before the rock pool is completely submerged again. A tough environment, while many can't survive, many others, as featured in this issue, can survive and thrive.
