Zizania latifolia is a large semi-aquatic grass from China that has run rampant on riverbanks, ditches in parts of the North Island from Northland to the Kapiti Coast. It is abundant on the margins of Northern Wairoa River in Northland.

It is tall rhizomatous, perennial, grass that grows up to 3 m tall. It has long, straight, light to dull green leaves that grow in fans. The leaves are 2- 3 cm wide and up to 2.5 m long and have a stout midrib and taper to a point. During November, December it develops a reddish-brown flower head that is 40- 60 cm long. Established plants spread by long, stout rhizomes and form densely impenetrable swards. The seeds are spread by water or by drainage machinery.

Zizania latifolia is real problem plant because it replaces all other species. It also causes silt to accumulate causing flooding which destroys aquatic flora and fauna habitats.
