Yes, Michael Hill, Jeweller indeed. Presumably it's the same person.
When I was living in NZ I was nearly driven mad when watching TV by the number of irritating advts for "Michael Hill Jewellers". The message was relentless and delivered in much the same way as whatever product was being advertised with the bloke offering the set of steak knives and that dreadful phrase, "but wait, there's more......".
However, obviously it worked for Michael Hill. Sounds as though he's fairly seriously rich these days.
