Bernard Hickey details the top 10 charts for 2010 in association with Bank of New Zealand, including this chart picked out by the Reserve Bank in its December quarter monetary policy statement.
It shows employment intentions and investment intentions in the National Bank's Business outlook survey going back to 1991.
It shows how these intentions have moved pretty much in tandem through various expansions and recessions until an apparent divergence since early 2009.
The chart shows that employers appear much keener to add staff but not to invest in new plant and equipment in the current recovery.
That is a worrying sign for the government and the Reserve Bank.
The broad hope was that New Zealand businesses and the economy generally would help transform the economy from being a borrowing and spending one into an investing and producing one.
The aim is to invest more in plant and equipment to make workers more productive, therefore improving productivity and eventually real per capita GDP.
The major weakness of the economic growth seen from 2004 to 2008 is that it was powered by overseas borrowing and by businesses adding more workers, but not necessarily improving productivity.
Growth without productivity increases can lift inflationary pressures, which in turn forces the Reserve Bank to run high interest rates and keep upward pressure on the New Zealand dollar.
New Zealand's per capita GDP has actually not improved since 2004, in part because of our very poor productivity growth. It may not be a coincidence that our weakness in productivity since 2004 happened at the same time as a long term slide in investment intentions.
Most agree that the best way to improve productivity is to invest in new infrastructure and plant and equipment. Giving workers better tools usually improves productivity.
So why are businesses so reluctant to invest? Are interest rates too high? Do they lack confidence in the future? Are exporters worried about investing long term because of the currency's strength and volatility? Are businesses being 'crowded out' by the growth in government spending?
Can we achieve the step up in economic growth talked about by Prime Minister John Key without that investment?
What can the Reserve Bank and the Government do to achieve that step up in growth?
Whatever that has been done doesn't appear to be working.
