The Insurance Council of New Zealand spokesperson John Lucas told Newshub buildings could become noncompliant through alterations over their lifespan.
"If a new service was pushed through a wall for a data cable, that ought to be recorded somewhere that can be inspected for compliance," he said.
Other examples of alterations affecting fire safety include missing smoke dampers in heating and ventilation systems and fire and smoke control doors that did not seal correctly.
The Insurance Council said in a statement the problem was concerning, considering the number of people working in tall buildings.
Mr Lucas said in some instances taking the stairs in the event of a fire may not be viable.
"These taller buildings require a modified form of egress, usually that is specially protected elevator systems," he said.
