The Liberals, who are aiming for a fourth term at the March 23 poll, want to introduce a protocol in 2026 requiring patients to be transferred from ambulances to emergency departments within 30 minutes.
The state's health workforce was expected to ease into the half-hour time requirement starting with a mandated 60-minute transfer window being rolled out in March before moving to 45 minutes in 2025.
The Australian Nursing and Midwifery Federation Tasmania took the government to the Tasmanian Industrial Commission to seek an order for the plan to be thrown out.
The commission blocked the procedure's implementation two days before it was to come into effect at three hospitals, determining there was insufficient consultation with stakeholders.
Federation members scheduled stop-work meetings at the Launceston General Hospital on Thursday and Royal Hobart Hospital on Friday to protest against the proposed rule.
The union's secretary Emily Shepherd on Saturday welcomed the status quo decision by the commission.
"It will enable further consultation to occur to ensure that ANMF members concerns and the risks they have identified are mitigated," she said.
"The ANMF empathise with paramedics who deserve to respond in a timely way to triple zero calls in the community and equally look forward to the risks transferred to nurses and midwives as a result of this procedure being mitigated to ensure timely and quality care throughout the patient journey."
The Labor opposition's Dean Winter said his party wants to take the pressure off hospitals by funding more staff and providing more services in towns and suburbs, labelling the government's policy a "slogan".
"This appears to be a plan that just moves people from the backs of ambulances on the ramp and into the hallways and cupboards of our hospital system," he told reporters.
"We need a comprehensive plan to take pressure off our hospitals and then once people are there so they can be treated within clinically-recommended timeframes."
Health Minister Guy Barnett has previously indicated patients would only be transferred if safe to do so under the policy.
The Australian Medical Association Tasmania's president John Saul labelled the policy to mandate the transfer of care as the "wrong way to go".
