Around 100 children have been admitted to Wellington Regional Hospital with respiratory illnesses in the past four weeks, health authorities say.
Health boards are aiming to increase capacity at Wellington's three hospitals in the coming years, with all still operating at a high occupancy.
On Tuesday Wellington's hospitals reported a higher volume of patients through emergency departments, and a very high number of children presenting with respiratory illnesses.
Hutt Valley and Capital & Coast DHB director of Provider Services Joy Farley said the volume was slightly lower today, but patients were still remaining in the emergency departments for longer than usual.
"Close to 100 children have been admitted to Wellington Regional Hospital with respiratory illnesses over the past four weeks, and around the same number has been seen in ED and discharged over the same period," Farley said.
