Direct investing in shares can be done through an NZX participant company but the level of service and information varies depending on whether you choose a transaction-only or full-service broker.
The cheapest option is through transaction-only companies like ANZ-owned Direct Broking or competitor ASB Securities.
Direct Broking managing director Mark Peterson said minimum levels of investment were set by the company which issues the shares but generally start at $500.
A new share issue such as the potential state-owned enterprise floats doesn't cost investors anything to buy into as the company pays brokers to sell it. It's once the shares list on the market that investors have to pay to buy or sell them.
Rates for Direct Broking start at $29.90 per trade for internet trading on the NZX of up to $15,000 and for ASB Securities the rate is 0.3 per cent of the amount invested or a minimum of $30 per trade on the internet.
