Your KiwiSaver is quietly changing New Zealand’s housing and future! Who can pay for the country’s housing and infrastructure?

What would you think if, one day, your retirement savings affected not only your quality of life in later years, but also whether this country could afford to build homes, maintain good roads and access reliable, clean energy?

We contribute to KiwiSaver every day, yet few of us have seriously considered a question: what else could this money do while it waits for us to retire?

KiwiSaver assets in New Zealand have already exceeded NZ$1400. The scheme is evolving from a personal retirement tool into a significant force that could influence housing, infrastructure and the energy mix. Today’s article explores a development that is already under way but remains poorly understood: if savings from across the population start flowing into nation-building, could that rewrite New Zealand’s growth model?

From saving to nation-building: Simplicity Living、Infrakiwi and a new model for housing and infrastructure

For decades, New Zealand’s wealth has rested largely on two pillars: property ownership and borrowing. KiwiSaver has introduced a third: domestic savings on a large scale.

Sam Stubbs believes this capital can do more than generate retirement returns: it can reshape housing and infrastructure.

“If this money is invested overseas, we earn a return, but it does not create jobs, growth or infrastructure here,” he says. “So how should we invest it at home?”

His answer has two parts: Simplicity Living and Infrakiwi.

Build-to-rent: treating housing as a long-term asset

Simplicity Living invests KiwiSaver funds in large-scale build-to-rent projects. This model is common among pension funds internationally, but implementing it on this scale is still new in New Zealand.

Its key distinction is vertical integration.

“We buy the land, we own the construction company, and we rent out and manage the homes ourselves,” Sam explains. This model removes what he calls “layers of puff-pastry fees”, which typically drive up construction costs.

Simplicity is currently building more than 1000 homes without using a cent of bank lending. This ability to operate against the economic cycle is crucial. The wider construction industry has struggled in recent years, but Simplicity has been able to keep building because long-term KiwiSaver money continues to flow in every day.

Members effectively hold a small ownership stake in hundreds of rental properties, a portfolio that will eventually number in the thousands. Even in high-growth funds, property exposure is kept to around 10%.

The social impact matters just as much. Many tenants are retirees who have sold their own homes but still need secure housing. Leases of up to 10 years provide that security. “Once your housing is secure,” Sam says, “you can spend your money on other things.”

Simplicity charges market rents, usually slightly below the top of the market. “We prefer to charge a little less to attract high-quality tenants,” he says. Returns are driven by long-term stability rather than maximising rents.

This creates what he calls a “fourth option” for retirement: long-term renting backed by KiwiSaver funds, with the funds themselves having an incentive to keep tenants settled and satisfied.

Infrakiwi: investing domestic savings in infrastructure

New Zealand faces an infrastructure funding gap of around NZ$100,000,000,000 to NZ$200,000,000,000. Traditionally, this funding has come from government borrowing or foreign investors.

Sam’s view is that the capital needed already exists within the country.

“There are twelve KiwiSaver managers nationwide, each of which will have billions to invest in the future,” he says. “They already hold vast pools of capital; politicians simply do not know their names.”

Infrakiwi has been proposed to bridge this gap.

The concept is to establish an infrastructure investment company listed on the New Zealand stock exchange for local investors, investing in long-term infrastructure assets. New Zealanders would own the equity, while debt financing could still come from international banks.

The investment horizon? “Essentially forever.”

If KiwiSaver invests through Infrakiwi, millions of New Zealanders will indirectly share ownership of roads, electricity networks, water systems and data infrastructure.

This long-term capital can smooth economic cycles. Sam points to Australia’s experience: 25 years of economic expansion supported by substantial pension fund investment. “They saved their way to prosperity,” he says.

Renewable energy and the “Chinese experience”

Energy is central to this vision.

China currently accounts for more than half of global investment in renewable energy and generates roughly twice as much electricity as the United States. Large-scale solar farms, nuclear power expansion and geothermal development demonstrate what capital deployed at scale can achieve.

Sam believes New Zealand has been too complacent. More than two-thirds of the country’s total energy consumption still relies on fossil fuels.

But new possibilities emerge when domestic capital becomes available.

Imagine solar panels installed on residential rooftops with no upfront payment, with financing costs spread through electricity network charges; surplus electricity fed back into the grid; and electric vehicles charged at close to zero marginal cost.

“These are becoming commercial realities,” Sam says. “We have both the capital and the technology.”

Within this framework, KiwiSaver funds do more than generate investment returns: they support the transformation of the energy mix, housing and national productivity.

A growth model that challenges convention

Simplicity’s model challenges two established assumptions: that finance must maximise shareholder profits, and that national infrastructure must depend on foreign capital.

In their place is a model of nation-building driven by local funds and centred on thinking across generations.

“We were only established ten years ago,” Sam says, “but we will be here forever.”

In his view, a new revival is on the way. Investment drives growth, and growth supports hospitals, schools and social stability. “Investment comes from savings,” he repeatedly emphasises, “and we are saving now.”

For Sam Stubbs, KiwiSaver is more than a retirement savings scheme. It is a lever for economic transformation, starting with every dollar.

For Sam Stubbs, KiwiSaver has never been merely a retirement account into which we save every day. It is a long-term force whose full potential has yet to be realised, capable of building security for individuals while providing patient capital for the nation.

As housing, infrastructure and energy begin to be supported by savings from across the population, are we ready to rethink returns, risk and fairness through a long-term lens?

What do you think?

Would you be willing to have your KiwiSaver invested in domestic housing or infrastructure?

Do you think nation-building should rely more on domestic savings, or continue to bring in overseas capital?
