750,000 square metres and counting
Calder Stewart does not build things that trend on social media. It builds warehouses, distribution centres and logistics facilities, the kind of structures most people drive past without noticing. But the numbers behind the Milton-founded, family-owned company are hard to ignore.
Over the past three years, Calder Stewart has delivered more than $1.5 billion in property projects and built more than 750,000 square metres of industrial buildings nationally. It holds roughly 900 hectares of industrial-zoned land from Auckland to Invercargill and says its volume of work could easily double in the next three to five years. This is private capital, no government subsidy, betting that New Zealand’s export economy needs dramatically more physical infrastructure than it currently has.
Hornby Quadrant is the Christchurch anchor
The most visible piece of the strategy sits in western Christchurch. Hornby Quadrant comprises over 150 hectares of prime industrial land at the crossroads of air, road and port connections. Calder Stewart spent almost two decades rezoning and building out the site from rural land. A 30-hectare Stage 4 release with titles issued went to market in October 2024, with a further 50-hectare stage still to come.
The precinct is attracting the kind of tenants that underpin supply chains rather than decorate them. Sorted Logistics, a national and international operator with over 200 staff, occupies a purpose-built 17,800 sqm distribution facility at Hornby’s Waterloo Business Park.
The market data supports the bet. Colliers data from March 2026 shows industrial land in western Christchurch now regularly selling above $400 per square metre, with smaller lots reaching $500/sqm. That still sits well below Auckland’s $1,000 to $1,500 per square metre, giving Christchurch a structural cost advantage for occupiers choosing where to base South Island operations. New-build warehouse rents run at $140 to $160 per sqm and prime industrial assets are trading at 5 to 5.5% initial yields.
Export growth is the demand engine
This is not speculative office development chasing co-working tenants. The demand story is rooted in primary sector economics. MPI forecasts food and fibre export revenue at $62 billion in the year to 30 June 2026, approximately 16% higher than two years earlier. Dairy, meat, forestry and horticulture all require more warehousing, cold storage and freight-ready facilities.
Ben Stewart, Calder Stewart’s director of property, says there is “increased demand for facilities linked to the primary sector” and that “occupiers want to build more efficient facilities to speed up the time it takes to send products overseas”. Cold storage is one of the most active investment areas. When a country’s biggest earners are perishable goods heading to Asia, the constraint is not demand for shed space. It is whether enough shed space exists.
Vacancy is ticking up, but context matters
Not every indicator is green. JLL data from November 2025 showed Christchurch industrial vacancy at 5.2%, a 280 basis point jump from the prior half. Western Christchurch sat at 5.7%, while Rolleston held at 3.5%.
The rise reflects new supply arriving faster than it is being leased, not a demand collapse. And the comparison with other asset classes puts it in perspective. CBD office vacancy has climbed to 11.3%, up from 8.3% in 2024. Industrial remains comfortably the strongest performing commercial property class in Christchurch. For tenants, the softening is actually useful. It creates brief negotiating leverage in a market that has been landlord-friendly for years.
The southern mega-projects dwarf the Christchurch play
Hornby Quadrant is actually the modest part of the pipeline. In Southland, Calder Stewart owns more than 500 hectares of heavy industrial-zoned land near Invercargill, where it plans an energy precinct worth about $3 billion including a wind farm. Linked to this is the Milburn Quadrant inland port south of Dunedin, with rail access and a planned value of $2.5 billion.
In mid-2025, RNZ reported the two southern projects had been costed at as much as $5 billion. John D’Arcy, Calder Stewart’s lower South Island business development manager, said at the time the projects would function as “integrated export and logistics hubs with direct access to two deepwater ports” and proximity to Manapouri’s renewable energy network.
These are long-dated bets. Tenant commitments for the Southland and Otago precincts have not been publicly confirmed, and projects of this scale depend on infrastructure investment and regulatory cooperation that can stall for years. But the logic is sound. If New Zealand’s export volumes keep growing and the logistics network stays concentrated in Auckland, the South Island’s cost and proximity advantages only widen.
What this means for business owners watching from the sidelines
Calder Stewart employs about 500 staff and projects 15 to 20% headcount growth if activity continues as planned. That is a signal in itself. While much of the commercial property conversation fixates on office downgrades and retail vacancies, the sector that actually moves goods, the sector that connects farms to ports and ports to markets, is absorbing serious capital.
The honest frame is this: Calder Stewart is making a multi-billion-dollar bet that New Zealand’s export economy will keep growing and that the physical infrastructure to support it is woefully undersupplied. The rising vacancy numbers in Christchurch suggest the short-term absorption story is not perfect. But a 70-year-old family company does not assemble 900 hectares of industrial land because it is guessing. It does it because the freight has to go somewhere.
