Mrs Skinner was given a closed-doors look at plans for the next stage of the $282.1 million redevelopment, before she toured the rapidly advancing acute services building.

The minister was flanked by member for Wagga Daryl Maguire and Murrumbidgee Local Health District (MLHD) staff for a hands-on check-up of the health facility's progress.

"This is a hospital that had been promised for a long, long time ... it's absolutely marvellous to see it rising out of the ground," Mrs Skinner said, as she addressed the media on level two of the new building.

"The people of Wagga and beyond deserved this facility years ago.

"In terms of country hospitals, you (Wagga) are one of the leaders.

"This is our biggest build, it's the biggest financial commitment we've made."

No additional information was provided by the minister, but The Daily Advertiser asked if further consideration had been given to the lack of parking at the site.

Mrs Skinner smiled as the question was asked - because it's a frequent one on redevelopment sites - but couldn't give a comprehensive answer.

"We've made that (parking) an essential element of all our big hospital builds and I'm very happy to tell you there will be additional car parking as part of stage three," she said.

"I can't give a definitive number but I suspect it will take the total to around 600 spaces."

Mrs Skinner also fielded questions about emergency waiting times and said improvements were being made across the health district.

"We've got to make sure our patients get the right treatment, in the right place, at the right time and to make sure they get the right diagnostics and are put in the right part of the hospital for their next level of care," she said.

Mrs Skinner said the circumstances were "far from optimal" for staff working in emergency.

"Which is why the extension of the emergency department in this building is absolutely critical," she said.

Mrs Skinner said the redevelopment was on time and on budget.
