In the end, there will always be a fundamental difference of perspective between New Zealand and Australia on defense, whoever is in government.

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

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'm not into power for the sake of it.

Innovation applied across the board of development is having a huge impact, and can have more. All sorts of technology can provide shortcuts, can overcome obstacles which once seemed insuperable.

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?

Never look back' is my philosophy.
