Hospitals before highways: New plan puts Canterbury’s big roads on ice

Tuesday, 17 February 2026

The commission’s modelling suggests cheaper safety and efficiency fixes could keep SH1 moving for years before a full motorway and bypass are justified.

Canterbury’s flagship motorway projects are no longer a sure bet, with the new national infrastructure plan signalling hospitals, power lines and repairs to ageing assets should take priority.

The 30-year plan, released on Tuesday by the New Zealand Infrastructure Commission, is essentially a scorecard of what the country can realistically build, fix or drop over the next generation.

Canterbury’s slice of the pipeline is about $15 billion compared with Auckland’s $109b, and all five South Island regions together account for only about $31b – close to a third of Auckland’s haul.

It leans heavily towards upgrading hospitals, strengthening the grid and replacing worn-out pipes. It leaves many of the projects politicians have talked up – including motorways north of Christchurch – still far from being funded or scheduled.

Users expected to pay more

New motorways, road upgrades and even some public transport are expected to be paid for increasingly through tolls, congestion charges, higher fuel and road user taxes, or steeper registration and parking fees, rather than simply out of general tax.

For Canterbury, the commission’s analysis suggests capacity north of Christchurch is not as pressing as political rhetoric implies.

For major projects including the Belfast-Pegasus section of State Highway 1, the Woodend Bypass and the proposed Christchurch mass rapid transit line, it finds capacity constraints are still some years away.

In many places, it argues, targeted safety treatments, resilience works, smarter operations and demand management can stretch the life of existing two-lane highways before expensive new construction is justified.

Mayor and MP push back on plan

Waimakariri mayor Dan Gordon rejected any suggestion the Woodend Bypass could be treated as a lower priority.

Waimakariri mayor Dan Gordon says increasing traffic only increases the risk for communities in his district.

Gordon said more than 20,000 vehicles pass through Woodend every day, which was only going to increase.

“The town is quite literally divided in two by the state highway and the risk this has posed for decades is not acceptable. As the community grows this risk only increases.

“I don’t think there is any suggestion the Woodend Bypass isn’t a needed major land transport project. In fact, funding is allocated and work is starting soon.”

He also pushed back on the report’s suggestion of more user-charging for roads, saying while tolling is proposed for the bypass, “the council is opposed to tolling charges” and has set out its reasons in a formal submission.

Waimakariri MP Matt Doocey rejected the idea SH1 capacity issues around Woodend are still years away.

“If experts think the date for exceeding capacity of the current road in Woodend is still some years away they clearly weren't stuck in traffic last Friday night after work like I was and what felt like most of Waimakariri.”

On funding, Doocey said: “A toll will be a decision for Cabinet but I’ve always been open that I support a toll if it means the new motorway and bypass will be built faster.

“With early implementation works already under way I look forward to turning the sod to start construction very soon as committed to by the National government,” he said.

The Woodend bypass is one of several South Island projects the new plan quietly shifts behind higher-priority spending on hospitals, power and basic repairs.

South Island projects also told to wait

It is the same story in other South Island regions, with the Hope Bypass near Nelson, the Queenstown public transport package and parts of the West Coast state highway network all flagged as corridors where pressure is building, but lower-cost safety and public transport fixes should come first.

The commission’s modelling suggests SH1 north of Christchurch and SH6 near Hope can be kept moving for years with those cheaper measures before a full four-lane motorway or new bypass is justified.

The same charts group Queenstown’s public transport upgrade with other long-term rapid transit ideas, treating it as a pressure point that can be tackled in stages rather than with one huge build.

Christchurch’s proposed mass rapid transit spine stands out for its uncertainty.

The commission cannot say with confidence whether existing roads and buses would hit their capacity limits in the 2030s, 2040s or later. It urges the city to lock in the corridor, sort out land use and ramp up bus priority first - instead of pinning everything on a fixed rail or track-based system on a set date.

While motorists sit in queues, the plan says the real pressure points are elsewhere.

Hospitals jump to the front of the queue

Health is one. The plan expects health infrastructure spending to about double as a share of GDP over the next 30 years to replace outdated facilities and add capacity for an ageing population.

A regional breakdown shows Canterbury will need more hospital beds and facilities by 2050, driven by both population growth and ageing, while the upper South Island and Otago–Southland face rising demand.

Electricity is another quiet winner. Decarbonising transport and industry will require more renewable generation, stronger regional grids and reinforced local lines, costs that fall largely on power users rather than taxpayers.

In Canterbury and the wider South Island, the pipeline highlights Transpower’s Upper South Island Transmission Capacity project, aimed at strengthening the grid feeding Christchurch and surrounding regions.

Underneath the maps and charts is a simple question: who pays, and for what.

The commission reminds ministers and councils that every project is ultimately funded either by users – through tolls, power and water bills, or congestion charges – or by everyone through rates and taxes.

With an ageing population and limited fiscal headroom, it argues, New Zealand cannot afford to build everything on the wishlist and maintain it all to a high standard. Choices have to be made.

It also pushes councils and government agencies to “recycle” parts of their portfolios – selling, leasing or redeveloping under-used assets – to free up cash for critical upgrades and renewals, rather than relying solely on higher rates, taxes or power and water bills.

The Government has six months to respond to the plan. Opposition parties have been invited to consult on the plan, with the goal of creating some level of bipartisan consensus on large projects.
