Londonderry MP Prue Car has been appointed deputy leader of NSW Labor, putting an end to weeks of party instability.
The former shadow education minister was elected unanimously on Tuesday, when the party also selected Penny Sharpe as Upper House leader and John Graham as her deputy.
In a statement, Ms Car said she is excited to work with newly minted leader Chris Minns.
"Like Chris, I understand the pressures on family budgets and the impact of the outrageous cost of (road) tolls," she said.
"Like Chris, I want to see our schools properly funded and staffed.
"It will be an honour to serve as deputy leader of my party and to help take a positive vision for NSW to the 2023 election."
With all leadership positions filled, the party is hoping to put a damaging few weeks behind them.
NSW Labor was thrown into turmoil when Jodi McKay resigned as leader on May 28, alleging destabilisation within the party.
The party seemed to be heading for a bitter ballot process to fill the newly vacated position, before former opposition leader Michael Daley withdrew from the race, leaving Chris Minns to be elected on Friday.
The focus will now turn to crafting a shadow cabinet.
