A payroll problem that has left DHB workers out of pocket is affecting other sectors.
DHBs have been miscalculating leave and shift allowances for nearly a decade, because of changes to the Holidays Act.
Spokeswoman for health professionals union APEX, Deborah Powell told Mike Hosking they owe past and present workers about $250 million.
She says the same problem has been found at MBIE, police and private sector employers.
"It's not the DHBs' fault because it's a widespread problem with payrolls, but it just wasn't picked up on."
