Munokoa Poto Williams MP (born 7 January 1962) is a New Zealand Labour Party politician and a member of Parliament.

[6] She moved from Auckland to Christchurch's suburb of New Brighton in January 2013 to take up a position as regional manager of the St John of God Hauora Trust but resigned from that role to run for Parliament later that year.

[16] In her first year as an MP, Williams was appointed to the Health Committee and was Labour's associate spokesperson for social development, the community and voluntary sector, and housing (Christchurch).

[18] In the 2014–2017 term, Williams served on the Health and Social Services committees and was Labour's spokesperson on disability issues and the community and voluntary sector.

The National Party challenged her nomination for the office because Williams had not been sworn in as a member of Parliament for that term yet.

Speaker Trevor Mallard dismissed the challenges because it is not a requirement for members of Parliament to be sworn in to be nominated as a presiding officer.

"[31][32] On 10 February 2023, Williams was granted retention of the title "The Honourable" for life, in recognition of her term as a member of the Executive Council.
