"We were chatting about that and it's something that I quite agree with – that she never came out of the closet because she was never in it."
Swarbrick said she was in a relationship.
Her sexuality has not been an issue widely broached in the media since she entered Parliament – something she is pleased about.
"I actually think that's one of the strong points in New Zealand media that we do, to a certain extent, just accept that people's lives are their lives when they go home from politics."
She said that in today's political climate, "liking people", as she put it, is not really a big deal.
Although she said New Zealand had come a long way in terms of the acceptance of different sexual orientations, there are still things that needed to be worked on.
"The debate we are currently having around transgender rights, in particular, gets pretty uncomfortable and the advocacy and the campaigning by former Green MPs like Kevin Hague, and also present MPs like Jan Logie, have always been really inspiring for me in that space.
