I only take on roles that I'm passionate about.

I think the issue of North Korea is one where the international community as a whole has to work to resolve the crisis.

In terms of protecting ourselves, the main issues are around how do we protect our borders [from illegal migrants and livestock and plant diseases], how do we protect our fisheries?

I felt really compromised. I think legal marriage is unnecessary and I would not have formalised the relationship [with husband Peter Davis] except for going into Parliament. I have always railed against it privately.

Girls can do anything. We do do anything and we expect to be treated as equals.

In terms of having views and being prepared to express them, yes, I think New Zealand's had a leadership role in a lot of things.

I deeply detest social distinction and snobbery, and in that lies my strong aversion to titular honours.
