Dear Rex 
Request made under the Official Information Act 1982 
Thank you for your email of 31 January 2022 requesting the following information under the Official 
Information Act 1982 (the Act): 
a copy of all email communications which discuss specific 2022 or 2023 opening dates for 
Transmission Gully 

Following receipt of your request, Waka Kotahi has undertaken a sweep of the email account of one 
staff member associated with the Transmission Gully project using a number of keywords associated 
with your request. This returned approximately 4,000 emails that would then require a manual review 
to determine which fall within the scope of your request.  
If this search was extended to all staff associated with the Transmission Gully project, we estimate that 
in excess of 5,000 documents would need to be assessed in order to determine if they are scope of 
this request. As such I am refusing your request under section 18(f) of the Act, as the information 
requested cannot be made available without substantial collation or research. 
Waka Kotahi will continue to keep the community updated with project news and the opening date on 
the project page. Our most recent update can be found at:
Under section 28 of the Act, you have the right to ask the Ombudsman to review my decision to refuse 
this information. The contact details for the Ombudsman can be located at 
If you would like to discuss this reply with Waka Kotahi, please contact us by email to 
[NZTA request email]. 
Yours sincerely
