His reply was to this Tweet:

125 yrs after white women were first given the right to vote (Māori women were fully engaged in democracy pre colonisation, and weren't able to be on the general roll till 1972, so yeah, universal suffrage not) here's the people who still can't.

And yet:

In 1919 the Women’s Parliamentary Rights Act gave women the right to stand for Parliament but it was not until 1935 that the first Māori woman stood as a candidate.

If a Maori woman stood for Parliament in 1935 how did they not have the right to vote until 1972? I cannot find any other information on that claim.
