The details of the sale of Margaret Mahy's Christchurch home are expected to be revealed in the next few days.
Mahy died in 2012 and had lived in the three-bedroom house in Governors Bay near Christchurch since 1968, where she raised her two daughters.
The cottage has a rating valuation of $640,000 and was on the market with a deadline sale which ended on Friday.
Her daughter, Bridget Mahy, owns the property and told the Herald it was too early to provide details of who, if anyone, has brought it but "things will be a little clearer" in the next few days.
