The latest pay round for school staff saw more than 350 people affected by payroll errors - fewer than the Novopay performance target.
Minister responsible for Novopay Steven Joyce has released the latest PricewaterhouseCoopers (PwC) report on logged complaints, showing errors affecting 0.42 per cent of staff.
The performance target is 0.5 per cent - which has been achieved in four of the last five pay rounds, Mr Joyce said.
In the previous pay period, 0.26 per cent of staff at 166 schools were affected by errors.
This is an improvement on error rates at the end of last year, which saw up to 2.2 per cent of staff at more than 600 schools affected.
