Data on wait times for emergency departments, operations and cancer treatment are now six months out of date.
In March, Te Whatu Ora was forced to pull inaccurate figures on emergency departments wait times from its website.
At the time National Party health spokesperson Shane Reti raised concerns about the figures and called them "gobbledygook".
He has regularly called for such data to be published publicly.
Reti spoke to Ingrid Hipkiss.
