Seaweek is New Zealand’s annual national week about the sea. It is hosted by the New Zealand Association for Environmental Education and includes a wide range of events, activities, competitions and opportunities for action.

With 75% of New Zealanders living within 10 km of the coast, marine science need not be limited to just 1 week, marine contexts can link to many different science concepts. Below is a sample of the Hub's marine resources. Use the Topics and Concepts links at the top of a page to find an even wider variety of teaching resources.

Below is a selection of unit plans and other teacher support materials that we have grouped under possible teaching topics.
