New Zealand does not have enough big companies to sustain the thousands of small businesses in the economy, says the New Zealand Institute of Chartered Accountants' chief executive, Terry McLaughlin.
The fact that so many Kiwi businesses seemed content to stay small might be restricting the country's economic growth, he said.
A report by the Ministry of Economic Development found 90 per cent of New Zealand enterprises employed five or fewer people, and 69 per cent were one-person organisations.
Massey University said only about 1200 businesses in New Zealand employed more than 100 people. SMEs accounted for 31 per cent of all Kiwi workers.
The report found SMEs, particularly those with fewer than five employees, were more likely to remain the same size over time than larger firms. They were also less likely to survive - the report showed almost half of SMEs were less than six years old, with very few older than 20 years old.
