I was incredibly stubborn. I mean, I believe that my father was frequently in the right, but I would never admit it, and so we did have a few set-tos on various topics; but on the whole as I got older and my father got more mature we got along reasonably well.

Life's a bit like mountaineering - never look down.

We had so much in common [with June Hillary] that we just carried on with life as we had been doing. It wasn't easy, but it was - I realise now that it was the only thing to do.

I have no desire to live anywhere else but New Zealand. I've had the good fortune to travel widely around the world, but New Zealand is home - and I like to be here. I'm proud to be a New Zealander.

I think I mainly climb mountains because I get a great deal of enjoyment out of it. I never attempt to analyze these things too thoroughly, but I think that all mountaineers do get a great deal of satisfaction out of overcoming some challenge which they think is very difficult for them, or which perhaps may be a little dangerous.

I think global warming is a very real problem for our world. I've seen the changes that have taken place in the Antarctic, in the Himalayas, where the natural ice has sort of faded away, and there's no doubt in my mind that we're living in a strange world, a world which is not easy to understand or handle, But there's nothing you can do about, you just have to live your life as best you can.

I don't spend a lot of time thinking about dying, but I like to think that I've - if it did occur - that I would die peacefully and not make too much of a fuss about it.
