While Ardern's wave was short-lived, interpreter Wendt's double-header version is much easier to copy.
In which the PM's sign language interpreter @alanjwendt delivers the double-header version of the 'East Coast Wave' - slightly more impressive than the PM's own effort https://t.co/Bf3pY3u8sS
Wendt later explained his expertise, saying he had lived for five years in South Auckland, five years in Porirua, and he was Samoan.
Interpreters don’t usu comment in public about our work. We do our job as Deaf people expect and require, their ACCESS is paramount. But for the record, as a kid I 1) lived 5 years in South Auckland 2) then lived 5 years in Porirua. And 3) I’m Samoan #AotearoaHard#FaiFaiPea 👍🏾 https://t.co/2MnESBxEca
Ngāti Kahungunu chairman Ngahiwi Tomoana told NZME "raising of eyebrows" had replaced the hongi or handshake as a greeting.
"The Kahungunu wave is the raising of the eyebrows in greeting, in affirmation, in exasperation, or in seduction.
"The nickname for Ngāti Kahungunu descendants over the past 200 years was Ngā Tukemata o Kahungunu, meaning the bushy eyebrows of Kahungunu."
Kahungunu was renowned for travelling solo throughout the country as others travelled in groups of warriors, in his time.
"Everywhere he went, he would help build and strengthen communities as he revealed his hard-working ethics by gathering food, building houses, constructing and designing pā," Tomoana said.
"The symbol of his multi-marriages, (some say eight, some say 13) was the raising of his eyebrows to attract or enact a romantic liaison."
This raising of the eyebrows is what the iwi referred to as the "Kahungunu wave".
"Every time he did raise his eyebrows or did the 'Kahungunu wave', a new hapū was formed."
In the iwi's history and traditionally the "Kahungunu wave" was as common and even more often used than the hongi, Tomoana said.
"In this pandemic 'coronavirus' atmosphere, we are urging all Ngāti Kahungunu to revert to our tikanga, the 'Kahungunu wave' – Te Mihi ā-Tukemata a Kahungunu," Tomoana said.
"It is all right not to hongi, it is all right not to kiss, it is all right not to hug, it is all right to put a rāhui [protective measure] around yourself and around your whānau and friends."
