- Ngongotaha Stream (Hamurana Road and Paradise Valley sites) is in a period of recovery following community riparian planting in 2006.
- All sites irrespective of surrounding land use show a decline in MCI scores at 2005/06, including the reference site, suggesting land use is not the driver of the decline in MCI.
- All sites, except the reference site show marked variations each year, suggesting vegetated riparian zone and surrounding land use protects the stream from abrupt changes.
