Dear Darren
Request made under the Official Information Act 1982
Thank you for your email
of 4 July 2023 requesting the following information under the Official
Information Act 1982 (the Act):
The SH2, southbound, Ngauranga off-ramp splits into 3 lanes before the traffic lights on the Hutt
Road intersection. One lane turns left and south onto Hutt Road. Two lanes go straight and
west.
This request is for:
•
the most recent traffic count data that separately recorded traffic from the off-ramp turning
left and traffic going straight.
•
data recorded after 2010 (maximum data age).
•
data in a .CSV file or other Excel compatible format.
•
a data dictionary to define each column of data (what it is, units, etc)
The information sought does not appear to be included in the State highway traffic monitoring
data. The monitor on the off-ramp appears to count all traffic in all lanes.
It is requested that the data is not conflated in any way. If the original data is recorded by the
minute, every 15min, or other, then that is the data requested. If the data recorded and
identified heavy vehicles or other types, that data is requested.
On 7 July 2023 we advised you that Waka Kotahi NZ Transport Agency is unable to provide traffic
data from the three lanes at the bottom of the Ngauranga Gorge, as a physical counter site does not
exist on the offramp to Hutt Road (SH2). We also advised you that Waka Kotahi could, however,
provide traffic data from three other sites in the area, and we asked you to clarify if you would like to
obtain this information.
As we have not had a response from you, I am refusing your request under section 18(g)(i) of the Act
as the information requested is not held by Waka Kotahi, and there is no reason to believe that the
information is held by another department or organisation.
Under section 28 of the Act, you have the right to ask the Ombudsman to review my decision to refuse
this request. The contact details for the Ombudsman can be located at
www.ombudsman.parliament.nz.
If you would like to discuss this reply with Waka Kotahi, please contact us by email to
[NZTA request email].
Yours sincerely
Josh Driscoll
Senior Manager, Research and Analysis
