Dear New Zealand Transport Agency,

Please provide information on the five environmental incidents over the three fiscal years 2020-21, 2021-2022, and 2022-2023 which were the most costly for NZTA in terms of the remediation measures they led to which NZTA paid for, or records containing that information. We are looking for the total cost per incident of the remediation measures and any report you prepared on each incident.

Under section 16(2) of the OIA our preferences are (a) to receive a copy of the whole document (b) that the information is disclosed in a text searchable format, either Word or PDF, and (c) that it is sent to the email address from which the Agency received this request.

If the Agency decides that there is 'good reason' under the OIA to withhold any of the information we are requesting, then under section 19(a)(ii) of the OIA, we further request that the Agency provide us with the grounds in support of each instance of a withholding reason cited for refusal. Guidance for agencies on how to meet their section 19(a)(ii) obligations is available from the Ombudsman at this location: https://www.ombudsman.parliament.nz/reso...

If you need to clarify anything in relation to this request, please get in touch.

Yours faithfully,

New Zealand Council for Civil Liberties
