Tough new measures designed to punish tech companies that fail to stop the spread of violent content on the internet are set to be rushed through Parliament, after federal Labor said it would set aside its concerns and support the legislation.

Prime Minister Scott Morrison last weekend announced plans in the wake of the Christchurch massacre to introduce laws would make it a criminal offence for online platforms to fail to rapidly remove "abhorrent violent material", including videos of terrorist attacks and murders.

Shadow Attorney-General Mark Dreyfus confirmed on Tuesday that Labor would not oppose the legislation, despite criticising the rushed timetable for its introduction in Parliament.

"Labor has serious concerns that this bill has been poorly drafted and will not achieve its intended purpose," he said. "[But] Labor will not stand in the way of this bill, despite our concerns."
