[3] Phyllocladus toatoa is a small, dioecious or monoecious, conical or bushy tree that grows to 15 m (49 ft) in height and 60 cm (24 in) in diameter at maturity on average.

[3] P. toatoa is distinguishable from other species in the genus Phyllocladus due to its whorled pinnate phylloclades with diamond-shaped segments.

[6] Phyllocladus toatoa can be found in lowlands and montane forests including the central North Island and northwards.

[3] Due to its tolerance of infertile soils, it can be found on exposed ridges, around bog margins, and other poorly drained land in New Zealand.

[8] The preferred habitat is that of a temperate climate with well-drained, moist soil, where roots are partially shaded and foliage is exposed to sun.
