The Election and Your Finances

New Zealand heads to the polls on 7 November 2026. The campaign is warming up, the polls are tight, and every party is making promises designed to win your vote. Capital gains tax. KiwiSaver changes. Tax-free thresholds. Infrastructure funds.

If you have savings, investments, or a mortgage, it is natural to wonder what all of it means for your finances. Over 160 years of market data, the answer is surprisingly consistent: elections barely move long-term returns.

Here is why, and what you should focus on instead.

Why NZ Elections Have Less Financial Impact Than You Think

Every election cycle follows a familiar script. Commentators speculate about which party is "better for the economy." Social media fills with confident predictions. Friends and family insist the country is headed for ruin if the wrong lot gets in. It happens here, in Australia, in the United Kingdom, and in the United States.

The pattern is remarkably consistent, and so is the punchline.

Vanguard, one of the world's largest investment managers, has studied portfolio returns going back to 1860. Their conclusion? There is no statistical relationship between election years and the performance of a balanced portfolio. A 60/40 portfolio, 60 percent shares and 40 percent bonds, has delivered broadly similar returns regardless of who is in charge.

Closer to home, the NZX 50 tells a similar story. Since its launch in 2003, the index has delivered a total return exceeding 500 percent, or roughly 10 percent per year annualised. In the same period, New Zealand has had seven general elections, five prime ministers, and governments from both sides. The NZX rose through all of them.

Research from the Economics Observatory, drawing on academic studies spanning decades, confirms the broader point: while share prices can wobble in the days around polling day, the party in power makes limited difference to long-term market returns. The real drivers of investment performance, including interest rates, corporate earnings, innovation, and global trade, operate at a scale far beyond what any single government controls.

New Zealand's Two Major Parties Agree on More Than They Would Like to Admit

This is the part neither National nor Labour will thank us for pointing out. Regardless of the rhetoric, both major parties broadly agree on several fundamentals:

• Neither plans to dismantle NZ Superannuation, the single largest line item in the government's budget.
• Both acknowledge the country's housing supply problem is partly driven by consent and planning regulations.
• Neither is proposing a wholesale overhaul of the tax system, even if they disagree on specifics at the margins.
• Both support New Zealand's general orientation toward open trade and free markets.

The differences are real, of course. But they tend to be narrower than the media would have you believe. New Zealand is not the United States, where the policy gap between left and right can feel like a canyon. Here, it is more like a creek.

What About the Policy Promises?

Both sides are making genuine policy commitments, and some could eventually affect your pocket.

Labour has proposed a 28 percent capital gains tax on investment property, with family homes and farms excluded. National has flagged increasing default KiwiSaver contribution rates from 3 percent to 6 percent by 2032. The Greens want a wealth tax. ACT wants less government spending. And as polling day draws closer, expect the promises to escalate. Election lolly scrambles are a New Zealand tradition: targeted spending commitments, tax adjustments, and giveaways designed to win votes in marginal seats. Every party does it. Many of the sweets quietly disappear once the campaign wrapping comes off.

These are real policy differences, and they deserve attention. But here is the critical point most people miss: campaign promises and implemented policy are very different things.

Under the Mixed Member Proportional (MMP) representation system, single-party government is rare. Coalition discussions frequently weaken, postpone, or remove policy goals, meaning the gap between campaign rhetoric and practical execution is often vast.

Take two examples of this friction in practice:

• Housing Targets: The last Labour government committed to building 100,000 homes, but delivered roughly 2% of that figure during its six-year tenure.
• Tax Policy: The National Party pledged a full repeal of the bright-line test, but ultimately opted for modifications rather than total elimination.

Beyond these specific cases, a frequent challenge for any governing party is the necessity of compromise. When power is shared, the original version of a proposal is often reshaped by junior partners or support parties to fit a broader consensus. This reality means that voters often see a significant difference between a party manifesto and the final legislation that emerges from Parliament.

The Real Risks Are Not Political

Here at Become Wealth, we are proudly apolitical. We do not have any political leanings or ties, and we do not make investment recommendations based on who is leading in the polls. What we do encourage is a focus on what you can control.

Most of the forces shaping your long-term financial outcomes operate well outside the reach of any New Zealand government. Global interest rate cycles are set by central banks responding to inflation, not by politicians. Technological innovation is driven by multinational corporations. Currency movements in the New Zealand Dollar are influenced by global capital flows and the monetary policies of much larger economies. Major geopolitical shifts, from trade conflicts to supply chain disruptions, are shaped by superpowers.

As a small, open, trade-dependent economy, New Zealand is largely a price-taker in global markets. A prime minister can shift the dial on domestic regulation and tax settings, but the forces above will have a far larger effect on your investment portfolio over any 10 or 20 year period.

The Costly Mistake People Make Every Election

The most expensive election-related decision is not voting for the wrong party. It is making a financial move you did not need to make.

T. Rowe Price, another global investment giant, examined S&P 500 returns across every presidential election since 1927. The difference between election-year and non-election-year returns is marginal and, statistically, could easily be explained by chance.

The same principle applies here. Selling shares because you are worried about a change of government, shifting your KiwiSaver Scheme to a conservative fund "just until the election is over," or delaying a decision to borrow and invest because of political uncertainty are all forms of market timing. And market timing, as the evidence overwhelmingly shows, destroys more wealth than it protects.

What You Should Actually Do Before the Election

Instead of reacting to campaign noise, the months before an election are a perfectly good time to focus on the basics. These are worth doing regardless of who wins:

1. Review your financial plan. Not because of the election, but because regular reviews are how good plans stay good. Are your goals still the same? Is your risk profile still appropriate? Have you ticked off some acheivements? Re-evaluate, then carry on.
2. Check your KiwiSaver Scheme settings. Are you in the right fund type for your age and retirement timeline? This matters far more than which party wins. Many New Zealanders are in default funds not well matched to their actual risk tolerance or time horizon.
3. Understand your tax position. If a capital gains tax on investment property does eventuate, it would apply prospectively, not retrospectively. Selling assets to avoid a tax not yet in existence, one which may never exist in its proposed form, is just speculation.
4. Keep contributing and stay invested. The power of regular contributions to a diversified portfolio, compounding over decades, dwarfs the short-term noise of any election. This is how wealthy New Zealanders tend to invest, and it is not a coincidence.

As Benjamin Graham, the father of value investing, put it: "The investor's chief problem, and even his worst enemy, is likely to be himself." Election season is when this rings truest.

Will the Election Affect House Prices or KiwiSaver?

Elections can create a brief pause in buyer and seller confidence, but the underlying drivers of house prices, including supply, population growth, interest rates, and credit availability, are far more influential. No New Zealand election in recent memory has caused a lasting shift in the housing market. If you are buying or selling based on your personal circumstances and timeline, the election should not change your financial outlook.

The same goes for KiwiSaver. Your Scheme fund choice should be based on your age, risk tolerance, and how many years you have until retirement. If you are decades away and in a growth fund, staying there through election cycles has historically delivered better outcomes than switching to conservative options and back.

And if Labour's proposed capital gains tax on investment property does pass? It would apply only to gains made after the start date. Making reactive decisions now based on a policy from a party not yet in government, subject to coalition negotiations it has not yet had, is premature at best. New Zealand has been debating a capital gains tax since the 1970s. It has not been implemented despite multiple attempts, by both major parties.

The Bottom Line: New Zealand Elections and Your Finances

Elections matter. They shape public policy, determine government priorities, and reflect the values of the society we want to live in. Vote thoughtfully, by all means.

But do not let the campaign reshape your financial life. The evidence, accumulated across centuries and continents, is clear: the best financial decisions are the ones made with a long-term view, a diversified portfolio, and a healthy indifference to the 24-hour news cycle. Governments change every few years. Compound returns work forever.
