GPS software for New Zealand

I have a Garmin GPS, does anyone have any first hand recommendations for mapping software for New Zealand?

I used to run these when I had a Garmin, they work great and best of all are free Dead Link Removed

If you'll be in the Auckland area at all I can loan you my little navman car gps, it's worth it's weight in gold!

Thanks Sean, very generous of you, I do have a GPS though. I found that link but it seemed a little problematic on my intel mac (running windows) . Have you ever seen this one?

I'll be flying into and out of Auckland so that does give us an opportunity to get together and try the local brew if you're available.
