Council chief executive Hamish Riach confirmed there had been some minor leaking from the glass atrium above the Pioneer Hall.
“The location appears to be at the edge of the flashing and it may be connected to recent work to replace a nearby double-glazed window.
“It will be fixed as soon as possible.”
The minor leak caused no damage, he said.
When the old library flooded again in November, library staff thought the move to Te Whare Whakatere marked the end of their water-woes.
Library manager Jill Watson has been at the library since 1975 and said, at the time, it was the worst flooding in the building she had seen, and hopefully the last.
The old building had become prone to leaking following earthquake damage.
The historic Pioneer Hall, built in 1916, was absorbed into the new complex and converted into a children’s library.
The old red brick building retained its walls and wonky chimney but had the roof removed, opening it up to the glass atrium.
Contractors replaced a faulty double-glazed glass roof panel in June.
The internal glass on the panel cracked in February and the safety glass has held it in place until a replacement was shipped from China.
