Christchurch has kicked off a global day of protests against Donald Trump's cutbacks to science funding.
The city has hosted the first of 500 science marches being held around the world today.
Marches are also being held in Dunedin, Queenstown, Wellington, Palmerston North and Auckland.
Canterbury University associate professor Bronwyn Hayward says the Christchurch event focused on how science is under threat.
She says speakers talked about why science and social science education matters, and how education is less expensive than ignorance.
