Upper Hutt's main library has been suddenly closed after reports revealed parts of it are earthquake prone.
As it is a public building, the Upper Hutt Central Library is classified as "Importance Level Three", meaning it has more stringent structural requirements than private places of work or residential buildings.
It has been closed until further notice and little is known of its fate yet.
"Careful consideration has gone into the decision to close the building," said Upper Hutt City Council chief executive Chris Upton.
"Ultimately, it is the safety of our staff and customers that is of primary concern to us."
