Where did the $4b go?

The NZ Herald reports on how the Minister of Health struggled to say what improvements in health we have had for the extra $4 billion a year he spends in the portfolio.

Hodgson did try and claim credit for decreasing infant mortality and increasing life expectancy, but these are trends which have been in place for over 20 years, and If I recall correctly, the rates of decrease and increase have actually slowed down in the last few years.
