Georgie Dansey, the chief executive of an education association, will contest the Hamilton West by-election for the Labour Party.
The by-election was forced by the resignation of former independent MP Gaurav Sharma.
Labour President Claire Szabó said Dansey -the chief executive of the Independent Schools Education Association and a small business owner - was a strong candidate for the electorate.
She also ran on the party list for Labour in 2020.
"Georgie's years of experience representing education workers and running her own business makes her ideally suited to advocate for Hamiltonians inside Government and ensure workers and business voices are represented," Szabó said.
"She brings a great perspective and represents Labour's values of fairness and opportunity in this by-election."
Dansey said the people of Hamilton West deserved a progressive voice inside government.
"In this by-election I want the focus to be on accelerating progress for our community. No one has benefited from the recent drama with the outgoing MP. It's time to move on and get back to focusing on the real issues Hamiltonians face, and I'm committed to working for Hamilton West on the issues that matter to them."
The Hamilton West by-election will take place on 10 December.
