Christchurch’s young turk developers have spent a decade trading donations and selfies for access and approvals. The architecture they are using is borrowed wholesale from Auckland — a corridor north out of the city, a local MP who turns the corridor into a fundraising base, and a property class that monetises the route the state is building for it.
Matthew Horncastle and Steve Brooks didn’t invent any of this. They’re just the first generation gauche enough to put it on Instagram.
The pattern
Every few months the NZ Herald runs the same story with a different face. Young Christchurch developer turns everything to gold, populates the society pages, donates to a political party, gets photographed with a Minister, then — sooner or later — turns up asking for a fast-track approval. Matthew Horncastle is the latest, but he is not the first.
Horncastle, the 32-year-old managing director of Williams Corporation, told the Herald’s Mike Thorpe last month he wants to be Prime Minister, would run through National “because that’s the only way to win”, donates to National, ACT and the Taxpayers’ Union, and is heading to a National fundraiser when Christopher Luxon next comes to Christchurch. A follow-up in February confirmed Williams Corporation is targeting a 2027 NZX listing. This is not coded language. It is a CV deposited in public.
His Instagram and Facebook fill in the rest. A selfie with Luxon at National’s Mainland Dinner — Horncastle says he paid $18,000 for two tables, including a $10,000 table beside the Prime Minister. A breakfast with Luxon on 23 April.
A lunch on 30 January with Chris Penk — Minister for Building and Construction, and the MP who inherited John Key’s old Helensville seat (now Kaipara ki Mahurangi). “Exactly the kind of person we want representing the country,” Horncastle wrote of the Minister who signs off on the regulatory settings under which Williams Corporation builds.
The offence, if there is one, lies in the picture that emerges when you put the posts side by side.
Where it came from
The Christchurch end of the pattern has a postcode. The Canterbury earthquakes pumped insurance money and uncontestable contracts into a city that had to rebuild its CBD and rehouse its red-zone residents. A handful made fortunes. A smaller handful made the political connections that would come in useful later.
The minister in charge of the rebuild was Gerry Brownlee, MP for Ilam, and current Speaker. Brownlee, Tim Hurdle and Chris Bishop worked as a close team through that period — Hurdle later sat as a Commissioner on the Earthquake Commission and ran campaigns for Wayne Brown and Mahe Drysdale; Bishop is now Minister for Infrastructure and the architect of fast-track.
The throughline from Brownlee’s office to today’s ministerial portfolios is not a conspiracy. It is the public record.
The Auckland template
But the playbook is older than the rebuild. I documented its origin at length in Unleashed: the Auckland-north corridor between Albany and Te Hana was the original laboratory. A political class on the route monetises the donor relationships the route creates; the developer class with land on the route monetises the asphalt the state lays down; everybody else pays for both.
The chairman of the NX2 Group consortium that financed the Pūhoi-to-Te Hana motorway PPP — with ACC as anchor investor at 38 percent — was Richard Didsbury, then the biggest developer in Matakana and Snells Beach, and founder of Kiwi Property Group. The developer with the most to gain from the corridor opening up sat on the board funding the corridor.
Paula Bennett was Waitakere MP and then Upper Harbour MP as the electorate boundaries were redrawn to capture the greenfield tradie growth at Hobsonville, Huapai, Kumeu and Riverhead — i.e., to follow the asphalt. She then walked into Bayleys as Director Strategic Advisory and, as I set out in “A very natural progression”, raised $1.8 million for National’s 2023 campaign “mostly from people in the property industry.”
And the precedent the National Party would least like discussed is Tara Iti. Former Prime Minister John Key personally lobbied the then-Forestry Minister Shane Jones to grant an Overseas Investment Act exemption so the US billionaire Ric Kayne could build a luxury golf course on land near Mangawhai — land iwi sold under contested circumstances, with surrounding aquifers later running dry from over-allocated water consents.
Key then hosted Barack Obama at the course.
A former PM intervened at ministerial level to facilitate a luxury golf course development.
That is the room the Wolfbrook brain trust would have looked at and concluded the air was breathable.
If Horncastle, Brooks, Key, or Bennett tried any of this in Australia, they would be investigated, thrown in prison, or chased out of town. In New Zealand, however, it's applauded in the society columns of the Herald, while any journalist questioning it is bullied by astroturfs, defunded, or the politicians themselves.
The Christchurch cut-and-paste
The Christchurch Northern Corridor is now following the same arc.
NZTA lodged its main works applications under the Fast-track Approvals Act in late 2025, with construction running through and past the 2026 election. Wolfbrook acquired the 77.66ha Pegasus golf course — sitting almost exactly at the corridor’s northern landing point — through a mortgagee sale in April 2026. It donated $40,250 to the National Party on 23 April 2026, disclosed the following month, in the same window as the acquisition. It then announced it would seek to rezone the course for housing.
One industry figure called the rezoning, if granted, potentially “the deal of the century”. The donation, the purchase and the motorway extension landed inside the same fortnight.
The question of who knew what, and when, is one the Auditor-General — already inquiring into fast-track conflicts of interest — might find interesting.
The Max Key template
There is also a stylistic lineage to draw. The performance of political proximity — the rich-kid Instagram of standing next to power and posting the photo — was pioneered by Max Key. By his own later admission to Stuff, he spent the back half of his father’s prime ministership portraying “a party-boy, drop-kick version of myself” — the #JohnKeyDoingStuff hashtag, the YouTube vlogs, the dabbing with Dad, the twerking with David Seymour.
He later said he regretted the portrayal. By then the template was set: visible proximity to political power, presented as personal brand, monetised through the audience the proximity generates.
Horncastle and Brooks are running the same playbook with property-developer money instead of inherited-PM money.
Horncastle’s Mainland Dinner selfie is a Max Key post with a different surname.
Brooks’ 2019 “rogue” National advertisement promoting Christopher Luxon — from a property developer also running the payday lender Moola — was the prototype of the same impulse.
Both men donate to the Taxpayers’ Union as well as the parties; that triangle of National, ACT and the Taxpayers’ Union is, as I argued in “Astroturfs: Act Three of Dirty Politics”, the same money moving through three doors.
The donors know the doors connect. They expect the network to behave like a network.
The silent and the loud
A small disclosure. The McLachlan name has been in National politics since John McLachlan was Minister of Lands in the 1890s and Colin McLachlan held a portfolio under Muldoon. I am not directly related to either. The current National Party general manager, Jo de Joux, is married to John Key’s former deputy chief of staff Phil de Joux, whose mother is a McLachlan. Matt Doocey, whose Waimakariri patch the Pegasus rezoning sits in, is the nephew of former Speaker David Carter.
These are the people the establishment still produces. They are quiet. They went to the right schools. They do not put on Instagram who they had breakfast with.
The nouveau rich do.
When a Christchurch developer turns up in the Herald’s society pages, then on the donations register, then in selfies with the Prime Minister, then asking for a fast-track approval, he is illuminating, post by post, the architecture his party would rather keep in low light.
The party’s donor-base problem — which I set out in “The overhang trap” and in “The Bullshit Economy” — is that it depends on land-value appreciation continuing while the party publicly promises housing affordability. Horncastle and Brooks are the inconvenient evidence of which promise actually pays the bills.
A bridge too far
Pegasus may turn out to be Wolfbrook’s Arnhem. On D-Day the paratroopers took Pegasus Bridge in a textbook coup; three months later the same operation at Arnhem ended with them surrounded and captured.
Wolfbrook had the profile, the donation, the ministerial selfies, and a quiet mortgagee sale that delivered a championship golf course at around $9 per square metre against neighbouring residential land at $550. They thought they had taken the bridge.
Then Sir Richard Hadlee spoke. The residents organised. The Vining family wrote to the receivers. Mayor Dan Gordon found out about the sale the same Friday as everyone else. And Matt Doocey publicly opposed the rezoning.
Under Mike Thorpe’s “deal of the century” piece, a resident’s comment — “Us Pegasus Residents have a fight on our hands with the big bad wolf” — collected 136 likes.
The reply from David Hillier of Horncastle Homes, proposing residents accept a nine-hole course and “single level two-bedders with double garages” for over-fifties, collected 30 likes — many from people who work in the Christchurch construction industry.
The trade has shown up to defend the trade. That is also informative.
The spotlight problem
There is always one who cannot keep a secret.
RNZ has already established that companies and shareholders associated with twelve fast-track projects donated more than $500,000 to the coalition parties.
Wolfbrook’s $40,250 sits inside that pattern.
Williams Corporation’s ostentatious courtship of Cabinet sits beside it.
Doocey’s public break with Wolfbrook is the early sign the establishment is trying to isolate the link.
As I set out in “Flag debate now a political turf war”, the party knows how to isolate factions when it has to.
Nothing punctures a property-momentum campaign faster than a donor-developer trying to fast-track a wāhi tapu site against the express wishes of Sir Richard Hadlee.
The party did not invite the spotlight. The donors did.
Horncastle and Brooks are not the canary in the mine. They are the kids who lit matches inside it — walking through an underground network the Auckland-north corridor dug for them a decade ago, thinking they were shining a light on themselves and not noticing the incendiary stench.
The Auckland generation built this network. The Christchurch generation just blew it up, engulfing everyone sheltered by it.
