The NZX 50 contains New Zealand’s largest listed companies. Many pay fully imputed dividends, which matters for NZ tax residents. This page sets out factual information on a selection of NZX 50 companies, where to research NZX shares yourself, and the general risks of holding individual shares.
This page lists eight NZX 50 companies alphabetically, with their sector, what the business does, and approximate market cap and dividend yield (May 2026). Many NZX companies pay fully imputed dividends, worth up to 33% more than unimputed dividends at the 28% PIR rate. Company announcements, annual reports and share data are on the NZX website. Most individual investors who pick stocks underperform the index over 10+ years. This is general information, not financial advice.
Why NZX Stocks Matter for NZ Investors
The NZX is small by global standards (~$235 billion total market cap vs the S&P 500’s ~$60 trillion+), but NZX stocks offer a unique advantage: imputation credits.
When a NZ company pays company tax (28%), it attaches those tax credits to dividends. A shareholder receives both the cash dividend and the imputation credit. This eliminates double taxation — you pay income tax at your marginal rate, but offset the 28% corporate tax already paid.
For investors on a 28% PIR: A fully imputed dividend is effectively tax-free (the 28% corporate tax equals your 28% PIR rate). For a 17.5% PIR investor, you actually receive a tax refund on the imputation credits.

Selected NZX 50 Companies: Facts at a Glance
Companies are listed alphabetically. These entries are factual descriptions, not an assessment of any company as an investment, and the selection is not a recommendation.
Market capitalisation and dividend yield figures are approximate as at May 2026 and were not recorded with a source. Both change daily; check current figures on the NZX website before relying on them.

How to Research NZX Shares Yourself
- NZX website (nzx.com): each listed company’s page has its share price, market announcements, dividend history and periodic reports. Market announcements include results, dividend declarations and anything the company must disclose to the market.
- Annual and half-year reports: published on each company’s investor relations page and through NZX announcements. They set out revenue, profit, debt, dividends, and the risks the directors see in the business.
- Investor presentations and annual meetings: results presentations summarise the period’s figures; annual meeting materials cover governance and director elections.
- Companies Office register: holds each NZ company’s registered details, directors and shareholders filings.
- Disclose register (FMA / Companies Office): holds product disclosure statements and fund updates for funds, including funds that hold NZX shares, if you are comparing an index fund with buying shares directly.
- The FMA’s investor guidance (fma.govt.nz): general information on how share investing works and what to watch for.
General Risks of Holding Individual Shares
These apply to any individual company, on the NZX or elsewhere:
- Concentration risk: with a handful of companies, one company’s problems can have a large effect on your total. Holding 5–10 NZX stocks means roughly 10–20% in each; a 50-company index fund spreads money more widely.
- Company-specific events: earnings downgrades, regulatory changes, management changes or a capital raise can move one company’s price sharply.
- Dividend changes: dividends are not guaranteed and can be reduced or suspended.
- Market size and liquidity: the NZX is small by global standards (~$235 billion total market capitalisation), and smaller companies can trade in low volumes.
- Costs: brokerage applies to each trade, and frequent trading adds up.
- Track record of stock picking: most individual investors who pick stocks underperform the index over 10+ years.
Imputation Credit Value Calculator
For a fully imputed dividend at 28% company tax rate:
| Dividend | Imputation credit | Gross dividend | Tax credit received |
|---|---|---|---|
| $1.00 | $0.389 | $1.389 | $0.389 |
At 17.5% PIR: Tax = $1.389 × 17.5% = $0.243. Credit = $0.389. Refund = $0.146 per $1 dividend received. At 28% PIR: Tax = $1.389 × 28% = $0.389. Credit = $0.389. Net tax = $0. Dividend is effectively tax-free. At 33% (if non-PIE): Tax = $1.389 × 33% = $0.458. Credit = $0.389. Still pay $0.069 additional tax.
This is why fully imputed dividends carry little or no extra tax for investors on the 28% PIR rate.
Where to check the latest data
Rates, fees and returns change often. Before deciding, check current figures yourself:
- Sorted Smart Investor: compares fees, returns and risk levels of KiwiSaver and managed funds.
- Disclose register: holds each fund's product disclosure statement and quarterly fund updates.
- Financial Service Providers Register: shows whether a provider is registered to offer financial services in New Zealand.
- The provider's own website: has its current rates, fees and full terms; these change more often than any comparison page.
Frequently Asked Questions
Where can I buy NZX stocks in NZ? Through an NZX broker or share-trading platform; NZX access is offered by, for example (alphabetically), Jarden Direct, Sharesies, and Tiger Brokers. Brokerage fees differ, so compare each provider’s current fee schedule.
Are NZX stocks riskier than international index funds? Individual NZX stocks carry concentration and company-specific risk. A NZX 50 index fund holds 50 companies, and an international fund adds global diversification.
Do I pay tax on NZX dividends? Yes. NZX dividends are taxable income. However, imputation credits offset the tax already paid by the company. If held through a PIE fund that owns NZX shares, tax is handled at your PIR automatically.
