9:05pm: "I could sit here, we could pick over the results and talk about the margins and what they told us; but for the people out there, what matters is what we can do with it and what change we can bring," says Ms Ardern of her win.
"Here in Mt Albert there is so much to celebrate, but we need to go back to the basics - affordable housing, the ability to get around our city, clean spaces for kids to grow up in, water that you can swim in, creating the best schools and the safest neighbourhoods...
