New Zealand native orchid.

I have always known these orchids as Green hooded orchids, so decided to look them up, and found this link

Now I don't know which one it is!! (not sure if this link will work, as it is the first time I have done this)
It is quite common around our area, and there is a nice lot of them growing on the roadside, just along from our house.
