Te Whatu Ora has apologised for sharing inaccurate data that has prompted a please explain from the Health Minister, who had used the figures to talk up a turnaround in Emergency Department visits.
The health agency published the inaccurate figures on wait times in emergency departments, which showed some regions suddenly jumping to near-perfect scores.
The government insists no funding decisions have been made on the basis of the dodgy data.
