Notice the graph that Rod has obtained of normalised patents per country. See how NZ sits at about 0.5 in 22nd place. Finland rides at the head on 4.5 and the OECD average sits at just under 2 which means it's closer to Finland than NZ.
This is a graphic representation of the under investment in R&D in NZ compared to other countries. This isn't about centralised R&D run out of the government, but about the failing of companies to invest in product development. Great thing that Rod pointed this measure out.
