Funding of up to $804 million over 10 years has been announced for the second round of national science challenges.
In May, 10 national science challenges were announced by Science and Innovation Minister Steven Joyce and the funding for the first three released in October.
They are intended to focus New Zealand's research effort on the big science issues facing the country, he said.
Seven of the categories remain, including:
* Ageing Well - harnessing science to sustain health and wellbeing into the later years of life (up to $34.9 million over 10 years)
