New Zealand First MP Andrew Williams has blamed his low list ranking on a clash with the party's deputy leader, saying she sees him as a threat and wants him "removed".
Mr Williams has fallen from 3rd to 13th on a draft party list, meaning his re-election is highly unlikely. The finalised list is expected to be released this weekend.
The first-term list MP said the party's No 2, Tracey Martin, and party president Anne Martin, Tracey's mother, were responsible for his demotion in the rankings.
He said he had clashed with Tracey Martin ever since she became deputy ahead of him a year ago.
Mr Williams said he was now an outsider despite being the most experienced politician after his stint as the North Shore mayor.
