McCombs had earlier made two unsuccessful bids to enter Parliament: At the 1928 and 1931 elections.
McCombs – who was elected to the Labour Party's executive shortly after its founding in 1916 – had earlier become just the second woman to be elected to the Christchurch City Council.
After entering Parliament she was a strong advocate for New Zealand women, including calling for pay equity, pushing for the recruitment of women into the police force, and campaigning for better unemployment benefits for unemployed women.
For her services, she was awarded the King George V Silver Medal.
McCombs died in 1935.
