Ngapuhi kuia Titewhai Harawira and Ani Taurua are both vowing to bring the Prime Minister on to Te Tii Marae today at Waitangi.
Mr Key says he doesn't care who does the job.
The domestic tribal issue on the day politicians visit Waitangi had spiralled into something akin to a war drama, said marae spokesman Kingi Taurua.
He is critical of Mrs Harawira's refusal to give way to local leaders' wish for her to move on from the escorting job she established.
The Harawira whanau matriarch was present to bring on the Governor-General, Sir Jerry Mateparae, yesterday. Mr Taurua said Ms Taurua was refusing to give ground - meaning a potentially difficult day for both.
