Hi Roger,

Some years ago on a visit to New Zealand I found a music shop in Riccarton, Christchurch that was at that time a Technics dealer. The only listing I can currently find that may be the one is Sedley Wells Music Works, 103 Riccarton Rd, Christchurch. It may be worth contacting them to see if they can help. Phone is NZ 03 348 6357, Email is sedleywellsmusicworks@xtra.co.nz
Hope this helps

Len
