- A comprehensive study assessing the current state and survival of the formerly prolific pingao, or golden sand sedge, which has now become locally extinct in some areas of New Zealand.

They also present oral commentaries on the plant from key weavers from Kawhia/Maniapoto, Rarawa/Aupouri, Whanganui/Aotea, Tolaga Bay and Te Wai Pounamu.
