Valerie Kilfoil, a spokesperson with Service New Brunswick says in an emailed statement the systems were fully restored as of 5:15 a.m. on Wednesday.
She says the team will continue to monitor the situation over the next several hours as normal operations resume.
Computer systems are down at some New Brunswick hospitals following problems at a Saint John-based data centre.
But a spokesperson with Service New Brunswick, which manages the centre, says staff have zeroed in on what's believed to be the root cause of the problem.
"A substantial number of systems are impacted and teams have been working through the day and will continue to work throughout the evening to recover systems and ensure data integrity across systems is maintained," said Valerie Kilfoil in an emailed statement.
Kilfoil said the problems began with a "partial outage" at its data centre around 6 a.m. Tuesday, and the issue was soon escalated to the "highest priority" within the department.
"By mid-morning, vendors were on site with SNB technical staff to conduct diagnostic and repairs," she said.
The Horizon Health Network says the outage has "significantly impacted" its overall operations, but spokesperson Brent Roy says there has been "minimal" direct impact on patients.
"It has resulted in some cancellations in the Saint John area for some oncology patients," he said, adding that about 95 patients have been affected.
Applications that are used in other parts of the organization are also impacted by the outage, said Roy.
He said the biggest impact for the health authority is on the way things are done behind the scenes.
"To go from electronic processing of everything to manual certainly slows things down and causes things to get backed up," he said.
"As a result of that, we're bringing in some extra staff to Saint John to help deal with the backlog because it will need to be dealt with once the system comes back up."
Officials are not saying when the systems will be back to normal.
