Billionaire Kiwi entrepreneur Guy Haddleton has sold his luxury Northland beachfront estate for $40 million, more than four times its rateable value and nearly five times what he paid for it six years ago.
The sale of the 61ha property on Bream Tail Road, at Langs Beach, was brokered by Bayleys and comes just months after the agency secured the record-breaking $56m sale of neighbouring Andersons Cove.
Haddleton, whose "pizza economics" lesson this week ignited the election campaign and social media, bought the property in 2020 for $8.5m.
He confirmed to OneRoof that the estate changed hands in July for $40m but declined to identify the buyer.

OneRoof understands the purchaser is the same buyer who acquired the Nathan family's 48ha Andersons Cove estate next door in May for $56m, the highest price ever paid for a residential property in New Zealand.
The acquisition gives the mystery buyer control of more than 100ha of prime coastal land on one of Northland's most coveted stretches of coastline.

OneRoof approached the new Andersons Cove owner for comment but had not received a response by the time of publication.
Bayleys agent Duncan Ross, who brokered the Andersons Cove deal, declined to comment on the Haddleton sale but told OneRoof that farms and coastal properties were typically snapped up by wealthy buyers with links to New Zealand, as they were largely off-limits to everyone else.
Most exceeded the 5ha threshold for Active Investor Plus visa holders or were deemed sensitive land, which meant foreign buyers would need approval from the Overseas Investment Office, a process Ross said was far from straightforward.
"It's not naturally an overseas buyer because there's an extra step," Ross said.
However, New Zealand’s appeal was becoming increasingly apparent to wealthy buyers as they compared opportunities around the world, with high-end properties such as Andersons Cove highlighting just how unique the country was.
"I firmly believe New Zealand is the best place in the world and I think our buyers with the capability to buy properties of this nature are seeing that as well," he said, noting that Andersons Cove was bought by a Kiwi based overseas.

Ross said often the waterfront location was the defining factor, but people also wanted complete privacy as well as being close to Auckland. "Having farmland allows that, but it also allows buyers to grow their own food and raise their own livestock."
He said there seemed to be more of a trend towards these trophy farms, pointing to the sale of the 235ha Parihoa Estate in Muriwai at the end of last year.
"That provided the same sort of exclusivity. Close to Auckland again. When buyers look at these, they are looking at family legacy properties, and that little bit of scale gives them that."
However, while there were few properties like this, the number of buyers who could afford them was also small.
"The numbers would appear eye-watering, but we are talking about a very small number of properties," he said.

Haddleton and his late wife, Sue, bought their Bream Tail Road farm in late 2020 from an American former oil industry executive who had relocated to New Zealand.
That same year, they paid $8.5m for a headland estate a short distance away. Haddleton told OneRoof this week he has no plans to sell that property.
Haddleton's real estate moves have regularly made headlines. In early 2024, he put two neighbouring Takapuna beachfront homes on the market after shelving plans for a mega-mansion on the prized coastal site.
One of the properties, a four-bedroom Arts and Crafts-style residence designed by acclaimed architect Greg Noble, sold for $15.7m in December 2024. The second, a contemporary home designed by Brent Hulena, changed hands several months later for $12.5m.
"Life's journey involves many chapters. The sales of these two houses mark the end of one chapter and the beginning of a new one. As always, bittersweet," Haddleton told OneRoof at the time.
The Haddletons spent 17 years assembling the 2700sqm Takapuna landholding. Their European-inspired mansion, designed by Noble on the first site they bought in 2003, took more than three years to complete and involved hundreds of craftspeople.
Inside were Italian chandeliers, bespoke wallpapers and European furnishings sourced during overseas buying trips with Noble.
The couple expanded their holding in 2019, purchasing the neighbouring Hulena-designed home for $11.75m, before adding a third property on William Street for $5m the following year.
Plans to demolish the homes and replace them with an even larger Noble-designed mansion were abandoned after Sue's death in May 2022 and the death of the couple's son, Matthew, a year later.
"I am glad we did not do that for a whole host of reasons, not least understanding the sensitivity of those who have money and those who do not. It would have been obscene to have that on the beach," Haddleton said at the time.
Instead, he turned his attention to a substantial new home on the headland estate he has retained. Work began with Noble in 2023, and Haddleton told OneRoof this week that completion remains about 18 months away.
