District Health Board-employed radiographers are striking again.
Apex Union has announced more than 80 'partial strikes' across all 20 DHBs.
The strike affects radiology services such as general x-rays, CT and MRI scans and mammography.
The union says the latest pay offer from the DHBs was punitive and included a massive reduction in promised backpay.
DHBs have responded that talks have reached an impasse, and they are asking the Employment Relations Authority for help.
