Inland Revenue said it will hold off from using information from psychometric tests until a ruling from the Employment Court.
The Public Service Association has launched legal action against Inland Revenue over its plans to use psychometric tests on employees reapplying for their jobs.
Inland Revenue's chief people office Mark Daldorf said the organisation won't be using information from the tests during existing staff selection decisions until a ruling from the Employment Court.
"We have taken this decision with the interests of our staff front of mind, and to continue to provide them with the most certainty as soon as possible about their future at IR," Mr Daldorf says.
"In the meantime, we are proceeding with our selection process for the new positions, many of which are new specialist roles.
"Inland Revenue is committed to delivering on our organisation redesign and transition timetable as planned, and delivering a world-class tax system for all New Zealanders."
The Inland Revenue is planning to cut the number of its staff by around 30 per cent by 2021 as part of its business transformation plans.
Erin Polaczuk, PSA national secretary, said workers, many of whom had been with the IRD for years - were being coerced into taking psychometric tests just so they can reapply to keep their jobs.
