Frustration continues to simmer over pay parity for aged care nurses.

Aged Care Association Chief Executive Simon Wallace says a promise of parity was made at the end of November.

He says aged care nurses are paid up to 20-thousand dollars less than their counterparts in public hospitals.

But Wallace says that what has been delivered by Te Whatu Ora is less than half of what's needed.

He says it's short-changing our nurses, and it's going to cause more service disruption and see more beds closed.
