There were no declarations of interest recorded.
3. Identification of General Public Contributions
There was a short presentation from a member of the public, Frank Hill. He shared his concerns that ratepayers in Christchurch contribute most ($50Million) of the ratepayer basis for how the Canterbury Water Management Strategy is funded, yet he believes that most of this budget is spent in other more rural zones rather than Christchurch City. He also commented that Environment Canterbury raised rates by 20% last year. He also argued that the Zone Committee has given up its’ commitment to improving the health of Addington Brook and that Environment Canterbury should be paying to improve the health of Addington Brook, rather than Christchurch City Council. He also suggested that the Committee provide input to Environment Canterbury’s annual plan suggesting they put money into improving the health of Addington Brook and spend more of the CWMS budget in the city. Frank was argued that the stormwater treatment proposed as part of Christchurch City Council’s masterplan for Addington Brook is focused on cleaning up the water quality after it comes out of industrial and residential areas rather than stopping the pollution at source.
There were no deputations by appointment.

Committee Chair Annabelle Hasselman delivered a speech expressing the thanks and appreciation of the Committee to the winners of the Stormwater Superhero awards, Christchurch Ready Mix Concrete and Tunnel Wash for work that they have done ensuring their businesses implement practices which prevent pollution to stormwater and therefore also prevents pollution of waterways. Tunnel Wash received the Champion Stormwater Superhero Award, and Christchurch Ready Mix Concrete received the Stormwater Superhero Award.
Tunnel Wash was represented by Brian Court, Lesley Court, and Elliot Dowie. Christchurch Ready Mix Concrete was represented by Richard Sands and Clint Thompson.
The Committee noted that the recommendation referring to following up the awards by supporting these businesses with publicity of them as receivers of the Awards and stormwater superhero key messages is something the Environment Canterbury communications staff will work on if these businesses would like some support, rather than Committee members doing this themselves. |
|
Committee Resolved CWZC/2022/00020 That the Christchurch West Melton Water Management Zone Committee: 1. Award the Champion Stormwater Superhero Award to Ready Mix Concrete 2. Award the Stormwater Superhero Award to Tunnel Wash 3. Publicise the winners. 4. Provide assistance to the winners with sharing publicity about their awards and some of the stormwater superhero key messages, if desired 5. Reviews the award promotion and selection process to inform the development of an improved Stormwater Superhero awards programme for 2023. Oscar Bloom/Brynlea Stocks Carried |

The Committee commented that having a Healthy Waterways Action Plan for the main five catchments will be an excellent step towards further increasing the health of waterways throughout Christchurch. Committee members stated they are excited about working with their partners in Christchurch City Council and Environment Canterbury to achieve positive results. |
|
Committee Resolved CWZC/2022/00021 That the Christchurch West Melton Water Management Zone Committee: 1. Recognises and supports the Christchurch City Council initiative to develop the draft Healthy Waterways Action Plan and the opportunity it provides for implementing long term change for urban waterways in Christchurch. 2. Advocates for a collaborative partnership to build community engagement and political support for the Healthy Waterways Action Plan. 3. Collaborates with partners involved in the Community Waterways Partnership in this advocacy. |

Chrissie Williams presented to the Committee about erosion and sediment in the Ōpāwaho/Heathcote River catchment, Cashmere Stream and the tributaries of Cashmere Stream on behalf of the Ōpāwaho Heathcote River Network. Chrissie focused on sediment as a physical contaminant is a focus of the report. Water clarity is a useful measure of sediment and it significantly impacts the health of this catchment and water clarity is poor. Cashmere Stream water clarity has 85% of hill tributaries being rated as extremely poor. Sediment affects the water quality and aquatic ecology of the Ōpāwaho/Heathcote River. Erosion in the Port Hills is due to loess, a highly erodible soil that gets washed into waterways. Loess is made up of very fine particles that remain in suspension for a long time and prevent them from clumping together and settling.. Erosion is exacerbated by soil disturbance from heavy rain causing slips, tunnel gullies, slumps and stream-bank collapse; particularly where the soil has been disturbed and vegetation cover reduced by earthworks from agriculture and forestry work; cycle and vehicle tracks, road construction and fire. Controlling erosion and sediment on the Port Hills should aim to stabilise and prevent erosion before it gets started and prioritise steep north facing slopes with the highest potential for tunnel-gully erosion. Establishing and maintaining a persistent and healthy vegetation cover on the Port Hills is crucial to protecting these waterways. The amount of sediment and where it comes from varies between tributaries but a large amount of the sediment is most likely coming from the hill based tributaries in the Cashmere Stream Catchment. The Committee noted that that they would like to contact Chris Phillips from Manaaki Whenua Landcare Research who is conducting ongoing research into erosion and sediment control in other parts of New Zealand to see how their research could be utilised on the Port Hills, or whether local work is required. Manaaki Whenua has previously done erosion and sediment control research for Environment Canterbury on the Port Hills and Banks Peninsula. The Committee stated their wish to continue to support for and active commitment to, the Cashmere and Port Hills Working Group of the Zone Committee and the implementation of actions of this working group.

Committee Resolved CWZC/2022/00022 That the Christchurch West Melton Water Management Zone Committee: 1. Receive the background information on the status of the existing Cashmere Stream and Port Hills Working Group of the Christchurch West Melton Water Zone Committee. 2. Receive the information and suggested next actions from the Ōpāwaho Heathcote River Network. This results from the Network considering the knowledge shared at the joint July 2022 Ōpāwaho Heathcote River Network and Cashmere Stream and Port Hills Working Group sediment workshop and a literature and information review conducted afterwards. 3. Strengthens the effectiveness of the Cashmere Stream and Port Hills Working Group by: a. Recognizing the priority catchment remains the Cashmere Stream Catchment and Ōpāwaho/Heathcote River Catchment due to the scale of the problem in this catchment resulting from the catchment including the steep loess soils of the Port Hills. b. That any recommendations and actions based on this Working Group’s efforts be applied to the other main catchments in the Christchurch West Melton Zone where they are relevant and can be transferred. c. Establish a small task group of the Zone Committee to draft a revised terms of reference for this Working Group that strengthens its purpose, leadership and collaborative membership The task group is to share this draft with existing members of the Working Group to get their feedback, and then present a proposed new terms of reference to the Zone Committee at a future meeting of the Committee. 4. Engage with the Banks Peninsula Water Zone Committee and Whaka Ora Healthy Harbour group to seek to collaborate with them on improving erosion and sediment control in the Christchurch West Melton and Banks Peninsula water management zones. 5. Liaise with Christchurch City Council on the development and implementation of their Programme for Stormwater Port Hills and Lyttelton Harbour Erosion and Sediment. The budget for this programme begins in 2022-2023 and continues to 2030-2031, increasing gradually every year, totalling $9 Million over 10 years. Clare Piper/Mike Patchett Carried |
