So I'm useless at power and electricity but I'm looking at getting some LED lighting from the USA.

In short I need to get this sort of power driver

http://www.rapidled.com/0-10v-dimmable-nano-driver-with-potentiometer/

Attach it to a heat sink like this

And attach LED to the heat sink

My question is will our 220v kill such a system??

220 or whatever will be fine. The power module you linked to specifies it will accept anywhere between 100vac to 240vac as input.

According to your link, the input voltage is 100 - 240 volts, so it should work with our 230 volt system. It would need an NZ plug and an electrical safety certificate to be legal here I think.

I got this answer from the factory. 

The drivers can be run on power up to 240 VAC, and draw on average 0.9A.

So this is still okay?

That's exactly what you want to hear. It confirms the information provided in the specification and in the pictures on the website. Good result.

Some thoughts..

-
If you want more driver options take a look at http://www.meanwell.com/product/led/LED.html - they specialise in that style of driver in the LPF series - http://www.meanwell.com/search/LPF-40D/default.htm - as an example.
Add a pot or 10V to dim

I'd go meanwell - way more choice to better match you needed lighting.

XPG/2 are nearly as expensive as XML/2 - and are not as efficient. Cutter in AU gets some great deals on whites, as does Fasttech. Ebay/Fasttech sell amazingly cheap floodlight arrays with 30/50/100W of Cree chips for just a few dollars these days

For solder-free I think the new generation cobs from Cree and Bridgelux looks awesome. Buy direct from Digikey in the bin you require and thermal epoxy it to a spare Athlon or P3 HSF.
