Each of his direct descendants received a copy of his certificate and a centenary Olympic pin, ordinarily given only to Olympic athletes, at a ceremony organised by the New Zealand Olympic Committee last year.
The victim said the loss of the pin had saddened her and her family, but she remained philosophical.
"It's a broken world we live in," she said.
"Some young people don't have a chance these days.
"Their parents throw them out because they don't behave, and what do they have? Nothing."
She had lived at the address since 1978, and had been burgled once before, many years ago, the haul on that occasion including icecream (which the thieves, who were disturbed by a neighbour, wrapped in a sheepskin) and biscuits.
The only good thing that could be said this time was that the burglar had been tidy.
"He looked everywhere, but he didn't leave a mess," she added.
A police spokesman said he was following a promising lead in terms of identifying the offender, while the stolen property could be returned to the victim via the Kaitaia police station or the Northland Age.
