Dear David
Local Government Official Information and Meetings Act 1987: Request for information
I refer to your email dated 13 November 2021 requesting the information outlined below
provided to Environment Canterbury by Trustpower, as required under the National Water
Conservation (Rakaia River) Amendment Order 2013 (the WCO) for the last 5 years. Your
request has been referred to me to reply.
1. Al flow records (in cumecs) into Lake Coleridge from the diversions of the Harper,
Wilberforce and the Acheron Rivers. (as per S9A9(b) of the WCO).
2. Corresponding flow records (in cumecs) out of Lake Coleridge into the Rakaia Rivers
via the HEPS.
3. Records kept by Trustpower for the Lake Coleridge Hydroelectric Power Scheme (as
per S9A(3) pf the WCO) of the;
a. stored water within Lake Coleridge;
b. stored water that has been discharged from Lake Coleridge;
c. water (including stored water) being diverted into any canal from Lake Coleridge.
Environment Canterbury has decided to extend the date of reply for this requested information
under section14 of the Local Government Official Information and Meetings Act 1987
This request wil now be responded to on the 17 December 2021, instead of the originally stated
10 December 2021. Your request requires us to search through a large quantity of information
and meeting the original time frame would unreasonably interfere with our operations. The
reason for this extension is due to the complex nature of compiling & formatting the data
requested and the need to pull it into a single document to provide a response to your request.
You wil be aware that if you are not satisfied with this extension you are able to refer this matter
to the Office of the Ombudsman under s27 (3) of the Local Government Of icial Information
and Meetings Act 1987.
Should you require any further information or clarification, please do not hesitate to contact
Michelle Chung in the first instance ([email address]).
Yours sincerely,
Dr Tim Davie
