New Zealand First party representatives are putting on a positive public face after former Carterton Mayor Ron Mark was voted new deputy party leader by caucus members.
The decision comes after a tense week in parliament, where party members, including leader Winston Peters refused to comment on whether deputy leader Tracey Martin faced a challenge for her position.
However, speculation of a challenge was confirmed when Mr Peters issued a statement yesterday confirming the leadership change.
"New Zealand First is fortunate to have such high calibre Members of Parliament to contest caucus positions and the caucus is grateful to Tracey Martin for her serious contribution as deputy leader," Mr Peters' statement said.
Caucus voted on Tuesday and elected Mr Mark as deputy leader, with effect as of yesterday.
