This indicates, importantly, that the majority of small-firm owner-managers were investing in the face of the continued post-global financial crisis recession during 2009 and 2010.
What other countries in the world have such a high percentage of small businesses?
It is a bit of myth that New Zealand has a very high proportion of small businesses by international comparisons.
For example, a 2011 report by the OECD indicates that nine OECD countries actually have higher proportions of enterprises employing fewer than 10 employees, including Sweden and Australia. They certainly do not complain about having too high a proportion of small enterprises.
Secondly, whether we have the right mix and type of small businesses is a much more fundamental issue. For example, the lack of internationalisation by New Zealand's small businesses, and indeed NZ enterprises in general, could be seen as a failing.
A recent report by Statistics NZ, from their 2011 Business Operations Survey, indicates that only 18 per cent of businesses surveyed generated some form of overseas income last year and that 77 per cent of businesses had never generated overseas income.
This lack of internationalisation may be a reflection of New Zealand's distance from major overseas markets.
For example, Australia dominates as an overseas market and source of income for those businesses that do report international activity, reflecting the relative proximity of our nearest neighbour.
Should more small businesses be setting out with the ambition to grow big?
Some small businesses will have more growth potential than others.
For example, those with high growth potential, such as technology-based small firms, are likely to be in global markets from day one.
Relative narrowness of the sources of finance in New Zealand, such as an immature and fragmented venture-capital market, limits the capability of such firms to achieve their growth potential.
Easier access to finance may help such firms to achieve growth.
Not all small firms will wish to grow, but New Zealand does not have enough firms that achieve world leading growth, but remain here.
This is a more important issue than any debate about the proportion of large versus small firms in the economy.
It is an issue that will be taken up at a forthcoming small firms' conference, ICSB 2012, in Wellington, where creative high-growth entrepreneurs who have achieved world leading companies will discuss how they have overcome challenges of achieving high growth entrepreneurial firms.
