Household shareholdings outgrew the national pay rise 27 times over

New Zealand’s latest national accounts carry a split that should worry anyone selling to, employing or lobbying on behalf of ordinary households. In the March 2026 quarter, household compensation of employees rose just 1.2 percent, or $595 million. Over the same three months, household equity and investment share assets climbed 1.4 percent, or $16.4 billion. That is roughly 27 times the dollar growth in pay.

The percentages look similar. The dollars do not. A small rise on a large asset base swamps a small rise on a pay packet, and that is the quiet engine behind why so many New Zealanders feel poorer even when the headline numbers look fine.

Income grew, but not from working

Household net disposable income did rise 2.1 percent in the quarter, according to Stats NZ. But the lift came from entrepreneurial income, up 2.8 percent, and a lower tax burden, not from wages. Interest received by households fell 6.8 percent, so cautious savers lost ground while equity holders gained. Household net worth barely moved because a $9.9 billion fall in land value was offset by share gains.

Read that carefully. The family whose wealth sits in a mortgaged house and a pay cheque had a flat quarter at best. The household with a share portfolio or a business had a good one.

This drift is decades in the making

None of this is new. Back in 2018, Brian Fallow’s NZ Herald analysis of Productivity Commission research found labour’s share of income fell 8.3 percentage points between 1978 and 2016. The Commission calculated wage earners would have been $11,500 better off on average by 2017 had they kept their 1981 share. Then-director Paul Conway pinned much of it on weak productivity, which slowed from 2.9 percent a year in the late 1990s to 1.1 percent between 2008 and 2017.

A 2015 Productivity Commission working paper found something subtler. Between 1978 and 2010, real wages paid by firms rose 1.7 percent a year, but workers’ purchasing power grew only 0.8 percent, because consumer prices rose faster than the prices firms charged. Employers felt they were paying more. Staff felt they were buying less. Both were right.

The unions put their own number on it. The CTU’s 2018 bulletin estimated the falling labour share cost the average wage earner $2,122 a year.

Too little capital, in the wrong places

The instinctive response is to blame profit. That diagnosis is wrong. In 2025, Roger Partridge of The New Zealand Initiative argued that New Zealand had become one of the developed world’s most undercapitalised economies, with capital per worker lagging and an infrastructure deficit of more than $200 billion. Workers earn more when they have better tools, and New Zealand has not given them enough.

Where capital does go is the problem. In 2025, Craigs Investment Partners’ Jeremy Williamson told RNZ that $100 in local houses grew to $600 over 30 years, while $100 in local shares grew to $1,100. Property, he said, amounted to “buying and selling houses back to each other”. BusinessDesk’s 2025 investigation put the cost of this polite underperformance at $113 billion.

The tax system nudges the money that way. The OECD’s 2026 survey says New Zealand taxes housing lightly relative to financial assets and pensions, while corporate tax ranks among the OECD’s highest. It recommends shifting the burden toward withdrawals to build deeper domestic capital markets.

What the split means for your business

First, demand. Mass-market retail, hospitality and services depend on wage-driven spending, and that income is growing slowly. Premium and asset-linked spending holds up better. Businesses straddling both tiers should expect them to diverge.

Second, pay bargaining. When workers can see asset income outrunning wages, expect harder claims and more scrutiny of margins. Productivity gains you can point to are the best defence.

Third, tax risk. In 2024, the NZ Herald reported that an IRD study found the 311 wealthiest families paid roughly half the effective tax rate of middle-income earners, largely because capital gains go untaxed. Treasury’s 2025 modelling work now separates wage and wealth profiles explicitly to test how tax changes land. That analytical groundwork makes capital taxation easier to legislate, whoever forms the next government.

The fix is more capital, not less

The wage-capital gap is real, and pretending otherwise hands the argument to those who want blunt wealth taxes. The smarter answer is the one the OECD and the NZ Initiative point toward: stop tax settings from rewarding houses over factories, software and listed companies, and channel KiwiSaver money into productive local investment. Heading into the election, business should be making that case loudly. If it does not, the 27-to-one gap will be settled by someone else’s tax policy.
