Mercury NZ is a generator-retailer producing electricity almost entirely from renewable hydro and geothermal assets, alongside wind, and supplying power and telecommunications to retail customers. It is listed on the NZX and quoted in New Zealand dollars (NZ$). Our rating follows the HelloBrokers methodology: we weigh the fundamentals, the competitive position and the risks, and we do not publish made-up price targets or a fabricated analyst consensus.

7.1/10

Renewable utility

Best for Income-focused investors wanting renewable-utility exposure. Not for Investors seeking high growth or avoiding hydrology risk.

This is analysis, not investment advice. The bull case: an almost entirely renewable generation base, an integrated model, and investment in new wind capacity.

The bear case: output depends on hydrology, and wholesale electricity prices can be volatile. As with any single stock, returns depend on execution and the wider market.

Overall we see Mercury NZ as a renewable utility. It can suit a diversified, long-term portfolio for investors who understand the risks. As always, we do not publish made-up price targets.

There are two main routes, both of which should go through a regulated broker. A broker comparison is below.

Cash / spot

Buy the cash share through a broker

Open an account with a broker and hold the share directly in New Zealand dollars, with full shareholder rights and any dividends. New Zealand has no general capital-gains tax, so a gain on a personal, long-term investment is generally not taxed when you sell; New Zealand dividends often carry imputation credits. If you buy with the purpose of resale or trade frequently, Inland Revenue (IRD) can treat the profit as taxable income. This is the most direct way to invest for the long term. This is not tax advice.

CFD (leveraged)

Trade it as a CFD (leverage)

Some international brokers offer share CFDs. Leverage amplifies both gains and losses, the cost is the spread plus overnight financing, and you do not own the share. These international brokers are not licensed by the FMA and serve New Zealand clients cross-border. CFDs suit short-term traders who understand the risk; most retail CFD accounts lose money.

For most investors, buying the cash share through a regulated broker and holding for the long term is the most suitable approach. Compare brokers below.

To buy Mercury NZ, favour a regulated broker with low fees and good coverage of New Zealand shares. Compare them side by side below.
