NIWA Biodiversity Memoirs for purchase

The NIWA Biodiversity Memoirs are comprehensive, definitive, illustrated reference works that capture the rigorous, peer-reviewed scientific study of New Zealand’s distinctive marine fauna and flora.

The NIWA Biodiversity Memoir (NBM) series comprises technical works that describe New Zealand’s invertebrate marine life—sponges, corals, hydroids, worms, molluscs, crustaceans, sea stars and lesser-known groups.

They are beautifully presented, stand-alone monographs that reveal the history and diversity of the subject groups, with new species names and revisionary work that is relevant globally.

These important publications are indispensable references for academic researchers and postgraduate students interested in marine systematics and the conservation of New Zealand’s unique aquatic biodiversity, much of which is found nowhere else in the world.
