Talent2, the Australian company contracted to create Novopay, had been told it was "totally unacceptable," Mr Foss said. "We fully understand the school's concerns and have been as frustrated as them."
Mr Jones said the issues were causing stress at the end of the school year. "Because of Novopay I am not getting a lot of time to spend with the kids during their last week of school and this is a small operation. It shouldn't be a difficult operation for us. I actually feel sorry for the bigger schools."
Hawke's Bay Primary Principals Association president Rohan Pearse said not only was he dealing with issues of his own at Mahora School, but he was taking calls daily from other principals in the region.
"I am fielding numerous calls from principals every day about how to fix errors," he said. "It's a serious, serious concern.
"At the end of the day, the Ministry of Education is the employer and must pay their employees correctly. The concern also for schools is that there has been a significant number of extra hours put in by the payroll staff, and the extra payroll hours will affect staff budgets.
"At the moment I am just trying to support all schools and we are all trying to focus on celebrating the end of the school year on a positive note, and from a staffing angle it's extremely difficult."
Mr Jones said concerns were mounting as the holidays approached.
"The ministry needs to do something, we can't be expected to put other things aside."
