The success of a centre-right government under MMP has required the country to vote National and Epsom to vote Act.
That is set to continue. A failure by Act at this election would put at risk New Zealand's hard-won economic recovery.
There's a lot at stake. Our continued economic success requires Act to succeed.
I also have a philosophical reason for wanting Act to succeed. I think it's important to have at least one voice for freedom and reason in our Parliament.
Act provides a much-needed political counterweight to the other parties calling always for more government spending and ever-more regulation.
We need a champion for individual freedom and personal responsibility. Act is that champion.
I loved being MP for Epsom. The people were very good to me. It was a tremendous privilege to get to know the diverse communities and neighbourhoods in such a great part of our greatest city.
In my time, thousands of people came to see me from across the political spectrum, very often at the end of their tether. I was usually able to help. It was satisfying work.
I didn't want to go when I got the sack. As a minister in Government I was able to help Epsom people better than ever before and I finally had legislation under way to ensure better and more-principled government.
But that's politics. It wasn't to be.
And now the position of Act candidate for Epsom is open again. I am very pleased Act has excellent candidates in prospect. I have concluded it can't be me.
I now don't have the necessary passion and enthusiasm to do the job well. Yes, I loved it and I gave it everything I had. And then some. But it's gone now. I am not sure why that is. It just is.
There was a time when Winston Peters could rattle an entire government, bringing ministers to their knees. Now, even junior ministers get the better of him.
I think it's sad. Peters appears like some aged rock star who has partied way too hard and is now up on stage trying to relive the glory days. Or perhaps a champion boxer who has stayed too long in the ring. I wouldn't want that.
I thought the worst thing for Peters was getting dumped in 2008. No. The worst thing for Peters was getting back in 2011.
New MPs snigger at him. There was a time he would have swatted them down like flies.
I prefer to remember Peters as he was. He's a salutary lesson.
I have a project under way in Christchurch. We have a third baby due in July. I have new and different challenges ahead.
Last week I came out of the airport and there was a Crown limousine. It was like old times. The driver asked if I was planning a comeback. I said no.
I walked past the limo, past the taxis, to the bus. I laughed all the way home revelling in life's twists and turns.
