Yeah, the greymouth tour was nice - when I was there they had a special on tap, a very tasty red ale, not too dissimilar from Porterhouse Red; said it was done by a trainee brewer who was on loan from Lion.
Quite liked a few of the others; baltic porter, summer ale, winter ale particularly.
Despite them ultimately being part of the conglomerate, the fact that they're willing to brew something other than fizzy yellow stuff makes them OK in my book.
