Kauri is considered a first rate timber. The whiter sapwood is generally slightly lighter in weight. Kauri is not highly resistant to rot and when used in boatbuilding must be protected from the elements with paint, varnish or epoxy to avoid rot. Its popularity with boatbuilders is due to its very long clear lengths, relative light weight and beautiful appearance when oiled or varnished. The timber has a beautiful sheen. It planes and saws very well. It holds screws and nails very well. It darkens with age to a richer golden brown colour. It does not easily crack or split or warp. Very little New Zealand kauri is now sold, and the most commonly available kauri in New Zealand is Fiji kauri, which is very similar in appearance but lighter in weight.
