The following is an excerpt from Aggie Nukus' Statement of Evidence for the Ngāti Kahungunu Wai 262 hearings in 2000. The statement is made in regards to weaving resources;
"It is very difficult to get other natural resources we need for our arts. It is not only the flax which has disappeared from its natural environment. Many other plants have also gone. One example is paupau, similar to a bull rush, and which we use to make sleeping mats. This has all gone".
The plant that Aggie is referencing is the Giant Spike Sedge (Eleocharis sphacelata). Depending on where you come from, this plant is given the names "paopao", "kuta" or "ngāwhā".
Paopao is one of the giants of Aotearoa New Zealand's freshwater flora when it comes to length - in suitable deep water habitats, it can grow longer than 4 metres from its base, providing most of the stem is underwater.
It is a prized weaving resource for a multitude of reasons; the fact that you don't need to hapine (soften) the fibre to work with it (as you do harakeke), its length and soft, spongy characteristic means it is a wonderful material for making tāpau/takapau (sleeping mats), and it has a range of natural colours.
