The Government is reducing its scrutiny of school teachers' marking of NCEA internal assessments.
Education Minister Anne Tolley told the secondary teachers union on Tuesday that the Qualifications Authority will double-check 50,000 fewer pieces of work next year.
Mrs Tolley says the focus of the checks will also change.
Of the 100,000 items likely to be analysed next year, only 5000 or 10,000 items will be randomly selected and used to calculate what proportion of teachers are making the right decisions.
The remainder will be chosen from achievement standards where teachers need more help and advice.
The secondary teachers' union, the PPTA, says the change will help reduce teachers' workloads.
