3.   Matters Arising from the Minutes

         Page 7, Item 8 – Ravensdown – Verbal Update – it was confirmed that the information about copper free brake pads on trucks had been forwarded to the company.


         Les suggested this matter should be promoted to other heavy vehicle industries also.  If Committee members have contacts, please forward the details to Lesley.


         Page 10, Item 12 – Zone Facilitator’s Update – a letter has been sent to the Minister of Health and notification that it had been received.  A copy was included under Item 7 of the 23 May 2019 agenda, titled Correspondence.  We are waiting for a response.


4.   Deputations by Appointment

A deputation was given by Adrianna Hess MSc titled “How Our Soil Will Save Our Waterways”.  This related to research into the difference between petroleum-based fertiliser and organic fertiliser, and how nitrogen persists in the environment as a result of each type of application.  The poor water quality of Te Waihora/Lake Ellesmere was referred to. 


The meeting noted an invitation to members had been received from the Selwyn-Waihora Zone Committee to attend their meeting on 6 August 2019 to discuss water related issues.  This would be an opportunity to ask the Selwyn-Waihora Zone Committee what farming practises are in place around Te Waihora/Lake Ellesmere and whether some of the suggestions presented by Adrianna had potential. 


5.   Identification of Urgent Items

         Lesley reminded members to email Liz Ryley if they have any additions to the Committee’s Register of Interests.


6.   Identification of General Public Contributions

         John Benn, Department of Conservation

         John referred to a lack of regional rules in the Christchurch West Melton zone relating to drain clearance and eels left on the river bank to die.  The regional rules need to be tightened in this regard.  Les advised that Te Taumutu Rūnanga does get notification of drains and dredging to ensure fish recovery, and this may be the case also for some of the other Rūnanga.


         Lesley will follow this matter up with Compliance staff and John Benn.


7.   Correspondence


Committee Comment

1.              In addition to the correspondence included in the agenda to the Minister of Health, the meeting had earlier noted an invitation members had received from the Selwyn-Waihora Zone Committee to attend their meeting on 6 August 2019 to discuss water related issues.

2.              Les suggested that the organisers of the Super Heroes should be involved in that meeting.



Committee Resolved CWZC/2019/00009

1.         Note the correspondence sent to Hon Dr David Clark on research on nitrate in drinking water and colorectal cancer risk.

8.   Community Water Partnership Activities


Committee Comment

1.              Clive Appleton, Team Leader Natural Environment at the Christchurch City Council, presented to the meeting on the Community Water Partnership Activities.  Feedback to date on the partnership has been receptive.

2.              Clive outlined the KidsFest Competition being undertaken from 6-20 July 2019 relating to blue fish about water from the roads washing straight into the river via the drains.  He responded to queries from Committee members.  He advised that it was important to improve communications, e.g. replicate the source to the sea bus trip to communicate to people in other catchments.

3.              There will be opportunity to include community groups in future.  Groups could be given blue fish to place around their areas.  Clive noted that the Volunteer Army wanted to put together a pack about stormwater to distribute to schools, and if that went ahead a blue fish could be included in each pack.

4.              Lesley tabled a document about volunteers on the Wairarapa Stream and an article on the Linwood fields, as referred to on the Christchurch City Council’s website, Newsline.

2.              The farming operation uses less water and leaches less nitrate in order to push the boundaries of best practice.  This is about the impact on the environment and about looking after people and providing them with adequate training.

3.              Shane and Ash responded to questions from members about the farming practices, that include the use of Ecotain pasture designed to lessen nitrate leaching from cows, and a range of biodiversity projects being carried out.
