I thought that South America would have been able to crack the 70C mark. It's barely more than NZ or Australia.
How about the difference between the coldest monthly minimum, and warmest monthly maximum? Coldest I can find for NZ, is Moa Creek at -4.6C in July, to 22.8C in January, for a 27.4C difference.
Wow,according to it Australia won by annual mean max/min temperature difference.
Althrough the places who has the highest annual extreme range here in Southern Hemisphere is somewhere in central Patagonia,Maquinchao is the best example,look its last year January and July :
I would expect South America and Australia to have greater annual ranges, but I think NZ has the greater continental effect (as opposed to continental influence)
That's because NZ can achieve a 27C difference only 80 km from the sea, while Neuquen has a 4C greater difference, but is 550km from the sea.

I guess the dryness is the reason for that,not continentality after all,New Zealand is too small for that,the dryness allow the larger diurnal range,but as you can see,the record low of Alexandra isnt very cold for its latitude,even BahÃa Blanca(38S/coastal location) has an colder record low,this is the difference between thoses places,one is affected by the the dryness and other is affected by an continental influence.
Coyhaique is other example,its at the same latitude and just 100m higher than alexandra,it also is very humid and cloudy in winter,but yet cold waves there can dip temperature below -15C or lower sometimes,with highs below freezing,how often this happen in Alexandra?

It would play a part, but would be even more so for Neuquen, which has only 40-50% of the rainfall of the NZ areas.
A thing to consider about Alexandra, is that all temperatures below about -7C/-8C happen with a heavy freezing fog, which acts to prevent temperatures dropping any further. It's summer maximums are also 7C warmer than Coyhaique, despite similar summer rainfall totals.
Areas to the east of Alexandra at only 300m, have still recorded lower temperatures than Coyhaique.
I think what Patagonia has, is the potential to see more extreme cold waves. Somewhere like Coyhaique, might see greater extremes, but I don't see it's averages indicate a continental climate at all. Even my town has a bigger range between coldest monthly minimum/warmest average maximum (at 23C compared to Coyhaique at 18.3C), and my town has an extra 500mm of rain, and is right on the coast.
How the heck can I regard Coyhaique as more Continental, when it's drier, higher, further inland, and yet has a 5C smaller range than my own very mild humid coastal climate?
NZ is always going to be more Oceanic, simply because it's an island(s) a good distance from major landmass, but despite that, can see a pronounced effect over a short distance, due to it's geography.
