Among the most valuable of all properties nationwide is an opulent clifftop mansion sold in 2013 to businessman Deyi Shi for $39 million. The 7-bedroom property at 4 Huriaro Place, in Orakei, today has a rating valuation of $46m.
It was reported last week that Auckland couple Simon and Paula Herbert had sold one of the city's most stately mansions, at 542 and 538 Remuera Rd for $25.5m to a family who came here from China.
This figure has not been reflected in the Homes.co.nz data provided to the Herald, because the sale is yet to be reflected on public records.
But if it did, it would sit in spot number four of the most expensive sales across Auckland City in the past five years.
Homes.co.nz has provided the top sales by region in Auckland, Queenstown, Christchurch, Tauranga and Wellington.
Auckland's second most expensive sale was the former Dotcom mansion which topped the list of nationwide property sales in 2016.
The Coatesville mansion went for $32.5m to proud new owners and Kiwi siblings - founders of toy company Zulu.
Renamed Mahoenui Valley, its new owners hope to scrub it clean of its former infamous reputation and make it a family home for future generations.
Outside of Auckland, the area around the luxury holiday town of Queenstown saw some of the country's most expensive sales.
A luxury property spread across 383sq m on Cardrona Valley Rd and marketed as a "private oasis" and just 2km from Wanaka was sold in 2015 for $13.8m.
A property on Queenstown's Brunswick St which sold for $9.3m the following year, came in as the area's most expensive sale in the past five years.
The holiday town of Mt Maunganui also saw some multi-million-dollar sales, with its most expensive property sold in the past five years a beachfront property in Omanu. The four-bedroom home sold for $6.2m in 2016.
In Christchurch the top sale came in at $5.65m for a five-bedroom home in the affluent suburb of Strowan, which sold in 2016.
Meanwhile the capital's most expensive sale was a 4-bedroom home built in 1928, which sold for less than its 2015 rating valuation of $4.5m.
The Wellington home on Oriental Parade was sold in 2017 for $3.78m, slightly more than the $3.215m it was bought for the year before.
Homes.co.nz chief marketing officer Jeremy O'Hanlon said the total value of all the top property sales across these regions still fell short of what was the most expensive sale in the United States in 2017 - a four-storeyed Bel-Air mansion, with 12 bedrooms, 21 bathrooms and three kitchens.
The American mansion, which also came complete with a four-lane bowling alley lined with gold pins, and two fully stocked wine sellers, was listed for a sale with an asking price of NZ$342.9m.
