WELLINGTON, Nov 2 - It will deliver one year of tertiary education without any fees and a $50 a week boost to student allowances.

The full programme of three years fees-free tertiary education will be rolled out by 2024.

Education Minister Chris Hipkins says planning for the first year has been fast-tracked so it can come in on January 1.

"Cabinet has given the go-ahead for detailed implementation planning," he said on Thursday.

"Officials have already started work."

Mr Hipkins said he knew students and tertiary education providers were keen to know the full details.

"We will make sure they get the information they need in a timely way - in the meantime they can rest assured that the first year of fees-free study will kick in next year."
