The ANMF Tasmanian Branch accepted the government's most recent offer on behalf of their public sector members on Wednesday.

ANMF Tasmanian branch secretary Emily Shepherd said the four-year offer addressed several key concerns.

"We know that this gives nurses and midwives the best offer across the public sector and we believe that this is recognition by the Tasmanian government of the dedication of the nurses and midwives working in the public sector under significant pressure," she said.

"We know that the offer will not address every concern ... and we have not achieved parity with other states and territories but this offer will considerably close the gap in the pay differential."

The ANMF signed a wages deal with the government in August, but were yet to work out other conditions.

Pay negotiations resulted in a 2.35 per cent wage increase for nurses and midwives in the public hospital system.

The agreed-upon conditions are aimed at attracting and retaining staff, Ms Shepherd said.

A government spokesperson said the decision was welcomed.

"Our nurses work incredibly hard across our health system and their pay rise is well deserved," they said.

"The four year agreement with the ANMF will deliver pay increases of 2.3 per cent in each of the first two years, and 2.35 per cent for each of the final two years of the agreement.

"The agreement will deliver increased professional development allowances to improve staff retention, and an Associate Nurse Unit Manager trial at the North West Regional Hospital.

"There will also be a review of the employment status of fixed-term staff, which will enable more staff to gain permanent employment."

The agreement will now be drafted and lodged, with back pay to be provided.
