Dear Mr T
Local Government Official Information and Meetings Act 1987
CAS-608940-B6P0D8
We refer to your request for information dated 1 November 2017 requesting information regarding the
Tetratrap catchpit screen.
Auckland Transport’s response to your request for information is as follows:
1) All costs involved in the development and design of the Tetratrap catchpit screen;
These costs are unknown to Auckland Transport as they were incurred prior to the
establishment of Auckland Transport and no records are available regarding the cost of
development and design of Tetratrap. Your request is therefore refused under section 17(e) of
the LGOIMA as the information requested does not exist.
2) Yearly construction and installation costs for the last 10 years. Please also provide the
number of Tetratraps this relates to;
Approximately 2800 Tetratraps have been installed to date and the cost range for
installation is between $850 to $1000 each, depending on size of existing catchpits and
road location.
10 year spend is in the range of $2.4 m to $2.8m (inclusive of professional services,
manufacture and installation).
3) Yearly maintenance costs for the last 10 years. Please also provide the number of
Tetratraps this relates to.
The yearly maintenance cost is estimated to vary between 10% – 30 % of the catchpit cleaning
cost over the last 10 years. This relates to the total number installed which was zero, 10 years
ago but now sits at 2800. The majority of these have been installed over the last 3 years.
We trust the above information has addressed the matters raised however, should you believe that we
have not responded appropriately to your request, you have the right in accordance with section 27(3)
of the LGOIMA to make a complaint to the Office of the Ombudsman to seek an investigation and review
in regard to this matter.
