papanga, n. 1. Site. Kotahi papanga kainga.
2. Layer, course. E rua pea papanga o te kareao, e toru ranei, ka oti (T. 154). Papanga rua or papa rua, twofold, of fabric.
3. Cause of discord. In the passage, Kia tika ki te uru, mo te tai awatea, mo Te Huakiwi; he papanga kei raro, kia rere maramara ki roto Taupo (M. 239). (Grey interprets as “dead bodies heaped upon one another, i.e., of two parties chief after chief is alternately killed for revenge; any one of them is said to be slain upon a papanga.” But it seems more probable that the word here has the meaning given above.)
