"This will in turn help to support regional development, create new jobs and lift incomes," Joyce said.
University of Auckland Professor of Physics Shaun Hendy thought the centres were "quite a good idea".
He said there was a risk, however, in fragmenting the science system, which is quite thinly distributed around New Zealand.
The $25 million is on top of the already announced $80 million increase for Callaghan Innovation's grants programme.
That funding, spread over four years, will increase the available Growth Grant funding from $102 million to $122 million annually.
Smaller Budget R&D announcements include a $1 million programme to attract big multinationals to undertake research in this country.
This will be paid for by reprioritising funding around the Science and Innovation portfolio.
As part of the Tertiary Education appropriation, Joyce earmarked $11.4 million over four years to boost the number of engineering graduates.
