Dendrobium cunninghamii is an epiphytic or lithophytic orchid herb that forms tufts up wide with wiry, cane like stems up to long and in diameter. The rhizomes are similar to the stems and produce many roots. The leaves are narrow linear, long and about wide. Up to eight flowers wide are borne on a short lateral flowering stem. The petals and sepals are white but some parts of the labellum are rose pink, purplish and green. The labellum has three lobes. The side lobes are erect, relatively small and pink or purple and the middle lobe has four or five greenish or yellowish ridges along its midline. Flowering occurs from December to January. The specific epithet (cunninghamii) honours Allan Cunningham. "Winika is the accepted old Māori language name for this orchid. The name Te Winika was given to the sacred war canoe of the Tainui people because this orchid grew on the tōtara tree (Podocarpus totara) which was hollowed out to form the hull. We assign the feminine gender to it—Winika cunninghamii. The Māori Queen, Te Arikinui Dame Te Atairangikaahu, granted consent to use the name Winika, because of its particular cultural significance to her Tainui people."

Winika is usually an epiphyte on forest trees but sometimes also on fallen logs. It sometimes grows on rocks and cliff faces, even on brick or concrete walls. It is found on both the North and South Islands of New Zealand but also on Stewart and Chatham Islands.
