Speights Distinction - Review from Arthur Dey

On my first visit to NZ in 1994 I was drinking Canterbury Draught in the Anglers Arms in Sefton with my mate Tom, and later discovered Speights Old Dark!!. I went back in 2000 to Picton and Tom and I continued where I had left off with the OD. While in the west country of the South Island in 2000 I became acquainted with Menteiths Dark and Macs Black. All of them very good. I cannot find an outlet in the UK for any of these beers, mores the pity. Can anybody help?.
