Houpara/coastal five finger (Pseudopanax lessonii) isn't locally native around Kāpiti but it's fairly common.

It easily hybidises with horoeka/lancewood (Pseudopanax crassifolius) to create Pseudopanax crassifolius × lessonii
The easiest way to tell whauwhaupaku/five finger (Pseudopanax arboreus) and houpara/coastal five finger (Pseudopanax lessonii) apart are by how houpara's leaflets join in the middle, while whauwhaupaku leaflets are on stalks.
The is also a mountain five finger (Pseudopanax colensoi). It doesn't appear to have a Māori name that I can find.

It is found in low alpine forest and scrub. It has thicker leaves and shorter leaflet stalks than whauwhaupaku.
Patē/seven finger (Schefflera digitata) can also be mistaken for whauwhaupaku/five finger.

It tends to be found in the understory rather than out in the open. It also has more leaflets and smooth leaf edges.
