The press gallery - the reporters based at Parliament - apologised in a statement.
“This afternoon, as MPs and ministers crossed the tiles into the House, Education Minister Jan Tinetti was accidentally hit in the head with a camera, while she was being filmed,” it said.
“The camera operator has since apologised in person and in writing. The Press Gallery would like to formally apologise to the minister for the incident.
“The Press Gallery executive will be reminding members of the expectation to be aware of their surroundings on the tiles to ensure the safety of MPs, staff and other media.”
Tinetti is a list MP based in Tauranga.
