* Kōwhai - This word refers to the kōwhai tree, which has beautiful yellow flowers. It could be used to describe the color orange, especially in a poetic or metaphorical sense.
* Karaka - This word refers to the karaka tree, which produces orange fruit. It could be used to describe the color orange if referring to the fruit itself.
* Whero - This word means red, but it can sometimes be used for shades of orange, especially if the object is more reddish than yellow.
