Libocedrus bidwillii is named after J. C. Bidwill, the New Zealand botanist and explorer.

However, according to DOC botanist Geoff Rogers, pāhautea is preferred correct form.

The seed cones are cylindrical, 8–12 mm long, with four scales each with a prominent curved spine-like bract; they are arranged in two opposite decussate pairs around a small central columella; the outer pair of scales is small and sterile, the inner pair large, bearing two winged seeds.

The timber in small dimension sizes is prone to spiral and twist when cut.

Severe possum browse can kill a cedar tree, leaving only stark stag head.
