High-profile newcomer MP Chris Luxon appears to be inching towards putting his name forward for the National leadership.
National sources have said former prime minister and Luxon mentor Sir John Key has spoken to at least three MPs making the case for Luxon.
Two of these conversations were Key returning a call from MPs who had contacted him first, but one was Key proactively reaching out.
Key told the Herald he was not calling around MPs to lobby for Luxon, but had spoken to a few who had contacted him to ask about it.
He had also rung one MP himself.
