A few years ago, I took a trip to Australia and brought back some Cadbury's Dairy Milk for a taste comparison to the local stuff, which was Irish at the time. (I also had some UK too.) It did not do well in the comparison and the general consensus of the Cadbury lovers in residence was that it could be a problem were one to move Down Under.
During my recent job interview visit to Wellington, I therefore made sure that I purchased a bar of NZ Dairy Milk for another taste test. Last weekend, we visited the same friends and before, bought some UK Dairy Milk and did a straight comparison.
Happily, for all those Brits out there who might worry about such things, the NZ Dairy Milk acquitted itself well. The general consensus was that it was a lot like Galaxy chocolate in the UK. Not quite similar enough to get a proper fix of Dairy Milk but certainly good enough to make to in between trips/visits.
(I also brought back some Hokey Pokey Whittakers chocolate, which was pretty good. My wife and I certainly polished it off quickly enough! )
