Mac's Brewery is in Stoke, Nelson, NZ which is in the middle of the V at the top of the South Island.
I grew up a few miles from the brewery and remember when it started. It was started by an ex All Black and the locals know it as Machasins which has subsequently been shortened to Mac's.
A few years back he ran into some health problems so did a deal with Lion Nathan where they would handle the distribution of the beer and his team would continue to brew it and have full control over the range etc.
With Lion Nathan doing the distribution the beers got really popular and exceeded the capacity of the Stoke plant. In partnership with Mac's they decided to start brewing the more popular lines (Mac's Gold) elsewhere (ala what LN do with the James Squire range).
With the Craft Brewing seqment taking off in NZ and Dominon Breweries having Monteiths as their craft range, LN decided to market the hell out of the Mac's name as their craft range. They even recently renamed the Shed 22 micro on the Wellington waterfront Mac's recently.
The pick of the beers for me is the Copperhop. I used to love Black Mac until one of LN's brewers refined the receipe and killed it. Still good but not great anymore.
Had the Wicked Blonde when I was over in Feb and it is pretty good. Not a session beer as there are a few too many botanicals in it, but still good.
Interestingly the Malt Shovel Brewkits are produced in NZ. In NZ they are marketed under Mac's name, with slightly different names for each kit (yet exactly the same contents).
