"While we might have one issue in any given pay period, this time there were eight or nine. We seemed to be making some progress and then with the change over we struck issues that set us back and set the Novopay relationship back.
"There's still a long way for Novopay to go before they get it right. Yes, it was improving but they've had a very long time to get things right and the latest pay round was certainly a step in the wrong direction.
"The issues took me away from other core tasks I could have been doing and it is still not completely fixed. It is annoying, frustrating and a waste of time and we find that as soon as something new happens, then a whole raft of issues arise.
"It's only through the goodwill of schools that we are still putting up with it. If this was a business, Novopay would have been dumped long along."
Mr Hodgkinson, who a year ago took up the presidency of the regional association, said the organisation represents more than 200 primary and intermediate schools in the greater Wellington region and his views on Novopay "are echoed by others".
Philip Harding, New Zealand Principals Federation (NZPF) president, said a federation survey conducted this week had provoked "a strong response" from 714 principals across the country, who reported that on average close to six staff members at each school had been incorrectly paid in the latest pay period and two thirds of the surveyed schools still have unresolved problems from last year.
"School principals report that the Novopay payroll system that caused so much chaos when it was first introduced is still struggling to deliver accuracy, and judging by their feedback, principals are still hugely frustrated at the inadequacies of a system that continues to suck their patience dry."
"We always expect the first pay round of the year to be a bit challenging but this error rate is way beyond anything we imagined," he said.
Mr Harding also was disappointed by the slew of problems unresolved from last year.
"Unsurprisingly, a whopping 72.7 per cent of principals have no confidence that Novopay is on track to providing an effective payroll tool that is fit for purpose," he said.
"Government has already poured millions of taxpayers' dollars into patching and propping up a payroll system that continues to let schools down, when it was supposed to create significant savings."
Mr Harding said principals "want to know when the government will finally acknowledge that Novopay can't be fixed and start work on its replacement".
