An review of the controversial pay system for teachers is to be carried out by an independent third party early in 2013.
The post-implementation review was revealed by Secretary for Education, Lesley Longstone, at an appearance before the education and science committee on Wednesday and was later confirmed by Associate Education Minister Craig Foss in a statement.
"There are several key milestones coming up including end-of-year and start-of-year payments, it is important they are captured by the review," Mr Foss said.
"It's also important that the review does not detract from the immediate focus of getting the payroll system running to its full potential," he said.
A spokeswoman for the primary teachers' union, NZEI Te Riu Roa, told NZ Newswire that there had been no improvement in performance in the latest pay round on Tuesday night and teachers were still reporting errors.
Novopay went live on August 20, 2012 and there have been thousands of errors.
Mr Foss again faced questions in parliament about why the introduction had gone ahead when problems had been encountered in testing.
He said questions should be addressed to the Novopay board and the ministry.
"I follow the recommendation of the expert panel, Ministry of Education and the Novopay board who recommended to me, after considering all such matters, that Novopay go live," he said.
Labour's Chris Hipkins said the independent review was welcome but until the terms of reference were known it was too early to say if it would be sufficient.
"Novopay has cost taxpayers $30 million already. The public and the parliament deserve to know what went wrong and why," he said.
