The Mortlach 70 whisky was distilled at Elgin, Scotland, in 1938 by the forerunner of specialist malt whisky distillery Gordon & MacPhail and bottled by the company in 2008 after 70 years maturation in a Spanish oak sherry cask.
It is the world's longest matured whisky to go on sale.
The cask produced 54 700ml bottles, at present selling for NZ$22,000 each, and 162 200ml bottles selling for NZ$5500.
The bottled whisky was unveiled in Edinburgh in March.
The 700ml decanters sold out immediately and two of the smaller bottles recently arrived at the whisky's only New Zealand destination, Meenan & Co in Dunedin.
Meenans managing director, and whisky connoisseur, John Eckhoff said it was barely believable that the whisky was 70 years old.
"We have 40-year-olds and 50-year-olds, but this is just phenomenal.
"It's so old you would have expected the wood to have destroyed the whisky."
Instead, the whisky had become more concentrated, the flavour more intense, according to reviews.
He had not tasted it, but got a "whiff" every time he opened the safe where it was stored.
"It's brilliant."
The bottles were being reserved for next year's DramFest whisky festival in Christchurch, where interested tasters could buy a measure of 20ml probably for about $550.
Mr Eckhoff was confident there would be 20 people interested enough to spend that much on a dram and that the other bottle would be sold.
