What does the word "versatile" mean.
Say I invite you to a South Island rabbit shoot tomorrow. You can only bring one rifle. There are also deer and the odd goat on the property (very real scenario, seen all three shot in one day with a .223). Does everyone have reloading gear? No. Can everyone get it in one day? No.
Are you going to bring your (insert centerfire here) the 300 rounds you will need, minimum, to shoot bunny covered faces all day?
.223 is the most versatile. You can get bulk ammo any ware, or a wide variety of factory ammo anywhere, you can take it on any hunt, for any game in New Zealand from the smallest in large quantities to the biggest.
This is not the "which caliber is the best for everything" question. 22-250 is a barrel burner. So that accolade goes to the compact 6.5s and 6mm rounds. Creedbore probably holds that title. The most boringly practical round ever invented.
If it was not for the region that is Otago and South Canterbury, then I would concede on the others. But these districts exist and there is a vast amount of fun to be had. You will need a bulk varmint rifle though.
If everyone hand loaded, I would concede on the 22-250 but it is also a barrel burner. Try shooting 30 rounds at a face multiple times, till the thing is white hot and see how long your barrel lasts. I put 30 rounds through my .223 two nights ago in a hurry and it was only warm. I have had a 22-250 (and will get another). I know the difference.
