What the grades mean

Each pack page names its grade. This is what each one means.

Heart1 pack: Mostly heartwood, the richer-coloured centre of the log.
Sap3 packs: Mostly sapwood, the paler outer wood, with a lighter, more even colour.
Heritage3 packs: Full of character. Pinholes and tight, sound knots in any number. Chosen for character, not a clear look.
Sap heritage1 pack: Sapwood with heritage character.
Mixed5 packs: Heart and sapwood together as they came off the saw, not sorted by colour.
Eucalyptus No. 16 packs: The mill's cleaner flooring grade.
Eucalyptus No. 26 packs: More natural features than No. 1.
Rimu premium, mixed colour1 pack: Select rimu with both light and dark colour in the pack.

Every pack is natural timber, so colour and features vary from board to board. The photos are of the actual pack.
