The drinking water supply at Taranaki Base Hospital's maternity unit has been given the all-clear follow pipe repairs and subsequent testing.
The hospital first became aware of an issue affecting the colour of tap water in the maternity unit in late June.
Acting Health NZ group director of operations in Taranaki Katy Sheffield said initial testing showed higher than usual iron content and the maternity unit shifted to the use of bottled water.
"Independent testing revealed this came from pipework in the maternity block's 1950s era building."
Sheffield said the hospital's infrastructure team then began working at pace to replace affected drinking water supply pipes.
"While the repairs took place, bottled water was supplied for drinking purposes to the maternity wards. Our hospital's infection prevention control team advised that tap water was still suitable for handwashing, and as per usual hand hygiene protocols, hand sanitiser was encouraged."
The replacement of the water supply pipework was completed on 26 July, and two subsequent rounds of independent water testing had reported safe drinking water levels with no residual iron content evident.
"We acknowledge the disruption while repair works were underway was a significant inconvenience to our patients, visitors and staff, and we appreciated everyone's patience and understanding over this time," said Sheffield.
"Our maternity staff and infrastructure team worked incredibly well together so we could safely look after our mothers and their newborns, and that repairs could be completed as quickly as possible."
A new maternity unit was currently being built on the hospital grounds as part of the Project Maunga Taranaki Base Hospital redevelopment project and would be open next year.
