After 29 days in Whanganui Hospital, Heather and her daughter Eva Margarette are back home.
"It feels really good to be a mother," Heather admits. "I never really thought I would be a mother and so I'm very happy with it.
"And I'm really happy that I have the ability to go out and show people I can campaign and I can have a baby and still do the things that are required of you".
While her boss, Jacinda Ardern, was challenged over her baby plans, Heather is proof that babies don't hold aspiring politicians back.
"The great thing about candidate forums is you get to talk about policy before the mix and mingle afterwards. And the mix and mingle is really fantastic because people genuinely want to know about my baby, they genuinely want to pass on their well-wishes and they take an interest.
"And sometimes I can steer it back towards policy. She is very helpful on the campaign but I don't want people to think I'm milking her for points."
And while it's a cliche politicians use to appeal to voters, there's not many who can get their photo taken with their own baby who they've recently given birth to.
