In the end, no matter how my records are panned or praised, if there are kids and communities in developing nations that have improved living conditions and are finally getting access to things we all have a basic right to (clean water, education, healthcare) because I am able to advocate, raise awareness or funds in some small way, then my life has achieved something that in the end means far more than having the track or album of the moment.

I had a pretty regular childhood, with a rad mum who taught me to love reading and thinking and laughing, and (as far as I was concerned) a regular dad who drove trucks for a living and did radio interviews on weekends and got stopped in the street a lot when we went out.

I know my sound, and I have to be true to who I am as an artist, even though I want be real cool, and make really cool music.

I have a particular style of writing and my voice sounds a particular way, which lends itself to a certain style.

I've always recognised that I have influence, whether I like it or not, and that I can use it to do something good.

Obviously, it was a big life change for me and quite a shock to suddenly have these songs I'd written in my bedroom as a far-too-intense teenager all over the airwaves and see my face on buses, especially in a small country like New Zealand, but at the same time it was such a thrill and an honour knowing that my music was reaching people.

I think I was always an old soul, even as a teenager.
