"There's no way I should have access to my pay, and Irene have access to her pay," Mrs Spencer told Fairfax Media.
"I can go in and do whatever I want to do, which is not good."
The two pay administrators demanded immediate action from Talent2, the Australian company which operates Novopay. By the end of yesterday they had been locked out of making changes.
Education Ministry group manager Rebecca Elvy denied to Fairfax Media the error had existed, saying the staff could not change their details without the changes being submitted by another person.
Last week the chief executive of Talent2, John Rawlinson, flew to New Zealand and apologised to school sector groups, and gave an assurance the problems with the system would end.
However Mr Rawlinson offended schools last week when he told Radio NZ schools were not "embracing" the new payroll system.
Talent2, which is believed to have a contract with the Education Ministry worth $100 million, is to be penalised $50,000 each time it bungles the fortnightly pay cycle.
