Chisholm Links, Dunedin, NZ
This course is out of the way from many of the others but you could swing a great road trip around the bottom of the South Island (called the Southern Smile)by flying into Christchurch and driving around to Queenstown/Wanaka.
Play Chisholm links in Dunedin, can't miss, its a true links, only two green keepers! Next, on the way to Invercargill stop in Fortrose and play the ultimate 9 hole NZ sheep track, conditions are soft in Winter but its worth a stop just for only $10 NZD. Then continue on to Invercargill and play the first 9 at Oreti Sands (after 9 its just dissapointing as it moves out of dunes on par with Barnbougle). Next play is Arrowtown just outside of Queenstown and I would seriously pass on Jacks Point despite the incredible views, the golf course probably has 9 good non-consecutive holes which connect you to some very average ones. If you must-- only play once. Continuing on your very scenic drive to Wanaka stop and play the Cromwell Golf Club, built on a glacial sand deposit, very rugged and enjoyable. After that loop around to play the front 9 at the Wanaka golf club, which looks over the beautiful Lake Wanaka then head down to the lake for a post round.
If my memory is correct, Each stop is 1-3 hours apart, you can probably get all this in 4 days and feel like you have seen some good golf and also been to a beautiful country. The only other two courses I would absolutely not miss are Cape Kidnappers and Paraparaumu
Tell me that doesn't look like a mirror image (literally) of Pac Dunes #4!
