About Kai Ho

Kai Ho ‘Oceans Treasure’ (also Tasmanian Sea Vegetables) is a business focusing on harvesting, processing and marketing seaweeds for the edible market. Primarily using Tasmanian sourced products, Kai Ho plans to be a leader in supplying Australian sourced edible seaweed products.  Building on the Tasmanian brand for excellent seafoods, Kai Ho are focussed on quality and reliability of supply.

Kai Ho was started in 2013 as a partnership between Dr Craig Sanderson, a seaweed biologist, and James Ashmore of Ashmore Foods Tasmanian, a major Australian seafood producer, processor and marketer. The products are marketed and sold through Ashmore Foods. All Kai Ho seaweeds are locally foraged and harvested sustainably.

Our principle product, the introduce algae, Undaria pinnatifida (also known as Wakame) was first discovered in 1988 on Tasmanias mid east coast. The alga has since been reported from St Helens (NE coast) to Dover (S coast) and on the Australian mainland at a number of locations on the Victorian coast. It was thought to have been originally introduced into Tasmania via the ballast water of ships trading from Asia. Undaria products form the basis of the Kai Ho product range.
