New Zealand First's defacto deputy Shane Jones has now been awarded the official title by his caucus colleagues.
The party has not had a formal deputy leader this term, though Jones has often been described by media in similar terms given his seniority and prominence.
In a surprise statement on Wednesday, the party announced the caucus had unanimously elected Jones to the deputy position.
"Shane has shown himself to be a relentless hard worker, loyal, demonstrate unquestionable passion for our country, and a megaphone for New Zealand First's views and principles."
It said Jones' appointment would give the party "certainty, direction and structure" heading into next year's election campaign.
Jones is also the Minister for Oceans and Fisheries, Regional Development, and Resources, and holds associate positions in Energy and Finance.
He entered in Parliament as a Labour list MP in 2005 and unsuccessfully contested that party's leadership in 2013. A year later, he resigned to take up a new role as Pacific Economic Ambassador.
Jones re-entered politics in 2017 as a NZ First MP until 2020, and then again in 2023.
The announcement comes shortly after NZ First's annual convention in Palmerston North, where leader Winston Peters predicted a massive political victory next year.
The event also saw former Labour minister Stuart Nash declare his allegiance to the party and float his interest in running as a candidate.
Previous deputy leaders for NZ First include Tracey Martin, Ron Mark and Fletcher Tabuteau.
