The Labour Party has not achieved everything it set out to during this term in Government

The Prime Minister said during her party's re-election campaign launch it's been three years of hard lessons.

Jacinda Ardern cited wanting more homes for first-time buyers and Light Rail in Auckland.

But Ms Ardern says when Labour hasn't reached its goals, it's been transparent.

She says they've had to accept when you try things that've never been done you don't always succeed, but you shouldn't give up.
