Questions about dividends


We aim to pay dividends of 70% to 85% of Free Cash Flow, subject to Board considerations. Dividend payments are usually made twice a year – an interim dividend in March (making up about 40% of the total amount paid), and a final dividend in September.

You can read our full Dividend Policy and find details of past and declared dividends on our website, on the Dividends page.


Not at the moment. Right now we don’t need the extra capital a dividend reinvestment programme would generate. It may be something we consider in the future if there are growth options that require new sources of funding.


Imputation is a mechanism that a company can use to pass on credits for income tax paid to shareholders when paying dividends. These imputation credits can offset the amount of income tax New Zealand resident shareholders would otherwise be liable to pay on the dividend income received.

For individual New Zealand resident shareholders, Mercury is required by Inland Revenue to deduct withholding tax at the top individual tax rate of 33% from the dividend before paying the shareholder. Where possible Mercury will attach imputation credits to dividends at the company tax rate of 28% which will offset the tax deducted from the dividend payment.

If a shareholder is on an individual tax rate below 33% they may be entitled to a tax rebate at the time of their annual income tax return. It is recommended that shareholders seek their own tax advice to determine the tax implications of a dividend derived from Mercury.


Where we can, we’ll pay what’s known as a supplementary dividend to shareholders who aren’t New Zealand residents. This offsets the impact of ‘Non-Resident Withholding Tax’. We receive a tax credit equivalent to the supplementary dividend we pay. There’s no disadvantage to us or our shareholders, and non-resident shareholders don’t get a larger cash dividend than an equivalent New Zealand resident shareholder.

We suggest getting tax advice about your own situation.
