Dear Timothy
Request made under the Official Information Act 1982
Thank you for your email of 3 November 2025 requesting the fol owing information about the Petone
to Grenada project under the Official Information Act 1982 (the Act):
…information and discussions regarding options north of Grenada.
The information I seek should include, but not be limited to:
-
Correspondence relating to future options to increase road capacity between the P2G
Grenada ramps and Transmission Gully
-
Information concerning BCRs of options
-
Discussion of maximising P2G benefits through increased road capacity north of Grenada
-
And any other information that is relevant to P2G's links north of Grenada
I am requesting information produced since Nov 2023, or since the beginning of the latest
P2G investment case phase, whichever is earlier.
On 13 November 2025, we wrote to you seeking clarification on the scope of your request.
Specifical y, we asked you to confirm whether all your questions relate to options considered for
upgrading the State Highway 1 (SH1) section between the point where Petone to Grenada would
connect with SH1 and Transmission Gully. You responded the next day with:
My questions relate specifically to options considered for increasing State Highway capacity
between Petone to Grenada and Transmission Gully. This may be upgrading the existing SH1
section, or through a new link road (a so-cal ed 'Takupu Link').
Such options were discussed in 2015 here:

I am requesting information later than Nov 2023 relating to similar schemes.
The work undertaken as part of the investment case did not consider options to increase state
highway capacity between the project’s proposed ramps onto SH1 and Transmission Gul y. I am
therefore refusing your request under section 18(e) of the Act as the document al eged to contain the
information requested does not exist.
Under section 28 of the Act, you have the right to ask the Ombudsman to review my decision to refuse
your request. The contact details for the Ombudsman can be located at
www.ombudsman.parliament.nz.
If you would like to discuss this reply with NZTA, please contact the Ministerial Services team by email
to [NZTA request email].
Yours sincerely
