At the Walters stood for parliament for the
Labour Party in the electorate and was ranked 22nd on the
party list. She became New Zealand's first Sri Lankan-born MP. Walters delivered her maiden statement on 2 December 2020, announcing an intention to address racism, human rights injustices and climate change and listing
Sir Bob Harvey,
Chris Carter and
Lecretia Seales as her mentors. During her first term in parliament she was deputy chair, and later chair, of the justice
select committee. She led the New Zealand delegation to the 2023
International Parliamentary Union meetings in
Bahrain, where she drafted an emergency resolution condemning
Russia's invasion of Ukraine, and
Rwanda. At the 2023 election, Walters once again stood in but was defeated by National's
Cameron Brewer by 11,192 votes. Walter's list placement was also too low to make it into parliament, making her one of the 14 first-term Labour MPs to lose their seat at the election. Following
David Parker's resignation, Walters returned to Parliament as a
list MP on 12 May 2025. She is the Labour Party shadow attorney-general and associate spokesperson on foreign affairs, and a member of the justice select committee. ==Personal life==
