Parliament’s Speaker Trevor Mallard says there are concerns about the earthquake strength of Bowen House.
Mr Mallard received a verbal update from engineers which outlined these concerns, although he stressed there was no immediate danger. A full report will be complete next week.
Mr Mallard says it’s almost certain some remedial work will have to be done but it's hoped this can be done a floor or two at a time.
Bowen House is located on Lambton Quay but is part of the Parliamentary precinct.
The 22 office block houses MPs like James Shaw, David Seymour, and Jami-Lee Ross as well as many staff.
