New Zealand Native Seaweeds

New Zealand’s unique marine environment is home to nearly 900 species of native seaweed, a third of which occur nowhere else in the world. Five of these native seaweeds were celebrated in this unique stamp issue.

Issue information

Seaweeds are an essential part of New Zealand’s marine ecosystem, providing food, habitats and shelter to a wide variety of marine life.

The New Zealand Native Seaweeds stamp issue reflected New Zealand’s remarkable marine biodiversity, and the five unique seaweeds portrayed are Hormosira banksii, Landsburgia quercifolia, Caulerpa brownii, Marginariella boryana and Pterocladia lucida. Each of the species is beautifully illustrated on a gummed stamp that contained the scientific name of the seaweed.

Native Marine Treasures of New Zealand

You could enjoy the New Zealand Native Seaweeds stamp issue further through the miniature sheet, first day cover and the miniature sheet first day cover. Each of these collectables featured illustrations of various seaweeds including a depiction of Durvillaea antarctica, Macrocystis pyrifera and Lessonia variegata on the first day cover, and the red Asparagopsis armata on the miniature sheet first day cover.

Single Stamp

Single 70c 'Hormosira banksii' gummed stamp.

Discovered by English naturalist, Sir Joseph Banks, Hormosira banksii is a common sight on New Zealand’s intertidal shores. Its distinctive beads have earned this seaweed many nicknames, including Neptune’s necklace, Neptune’s pearls, sea grapes and bubbleweed. Its beads are filled with gas, allowing them to float to obtain more sunlight.
