Labor's saying that's a total loss of four hour of time the Parliament could be spent working per week.
Minister Pyne's office confirmed the changes, saying they aim to "better manage the work of the House of Representatives".
"We have also moved the dinner break on Monday and Tuesday from 6:30-8:00pm to 8:00-9:30pm which is a more sensible use of Members time."
