The Government is putting another $2.8 million into Australia's synchrotron project to secure preferential access for Kiwi scientists.
The synchrotron is a source of intense light and is used for a variety of research projects.
Science and Innovation Minister Steven Joyce says it's the largest piece of scientific infrastructure in the southern hemisphere.
"New Zealand scientists have been enthusiastic adopters of synchrotron science," he said on Thursday.
"This renewed investment ensures they will have preferential access to the latest technology -- we're seeing more rapid and precise investigation of biological structures, diseases and medicine."
New Zealand has invested $120m into the synchrotron since it began operating in 2007.
