Oh, Max ... I am racking my brains but no luck. There is a name and I think it's similar to the Maori word. There was a delegation from OHA to the Maori in NZ and we had photos of one of the Trustees (Moses Keale ?) greeting a high ranking Maori in that manner as did other Trustees.
The subject of the greeting and its Maori and Hawaiian tradition was covered in the report of the visit. Also noted was that both languages had many words in common and when each spoke their own language the other could understand the gist of what was being said.
Sorry, still cannot think of it.
