Dear Jack Hulls 
 
Official Information Act request for information relating to the current earthquake 
rating of the TSB building 
 
Thank you for your Official Information Act 1982 (the Act) request received on 25 May 2022. 
You requested: 
 
“Can you please provide information about the earthquake assessment of the TSB 

building on Lambton quay. 
 
Of interest is when was it last assessed and what was the result. 

 
Any information about when another assessment wil  be done.” 

 
In June 2020, Parliamentary Services, which holds the master lease for the TSB building on 
Lambton Quay obtained engineering advice  from a structural engineering consultancy firm 
which seismically assessed the TSB building at 80% New Building Standard (NBS). 
 
After receiving this advice, Parliamentary Services then instructed another firm to undertake 
a peer review of  the initial  seismic assessment. After consultation between the two 
engineering firms, it was agreed that an 80% NSB rating was justified. 
 
A further Detailed Seismic Assessment is not currently scheduled. Unless new investigation 
methods are discovered, or there have been changes to existing building regulations, a 
regular testing scheme would not normally be in place. 
 
You have the right to ask the Ombudsman to investigate and review my decision under 
section 28(3) of the Act.
