In December 2000, a regime for monitoring the ecological condition and trend of the estuary was set up on contract for the Hawke’s Bay Regional Council by Geoff Walls. This was done using the experience gained in establishing a similar monitoring regime in Pekapeka Swamp in 1998, and in Whakaki Lagoon, Lake Poukawa and Lake Hatuma in 1999. It also had the benefit of the local knowledge of Department of Conservation staff. Baseline surveys of vegetation and fauna were carried out at the same time.
The results of the baseline survey and monitoring establishment were reported on (Waitangi Estuary Ecological Monitoring, December 2000). A companion report provided more background information and formed a plan for ongoing monitoring (Waitangi Estuary Ecological Monitoring Plan, December 2000). Hawke's Bay Regional Council produced a management plan for Waitangi Estuary in May 2002 (Cheyne & Addenbrooke, 2002). Ecological monitoring is factored into that plan.
In late November 2002, the estuary was revisited and the monitoring carried out for the second time, to determine the ecological condition and trend after two years. This document reports on the findings.

The purpose of this additional study was to determine how long it took for a site to comply with the bathing beach guidelines (action level) following a rainfall event and to determine what variable correlated most strongly with the high bacteria counts observed during this period.

Te Awanga and Haumoana are two small coastal settlements. As a result of the input from rural and urban runoff, contamination of these prominent features has been documented since 1992.

Tukituki Estuary (60 ha) is where the Tukituki River meets the sea. It includes Grange Creek and all the wetlands and associated riparian margins between the lower Tukituki stopbanks for a distance of 800 metres upstream of the mouth. It is contiguous with the Waitangi -Muddy Creek wetlands. Although much of it has been modified over the last 100 years it is still ranked highly by the Hawke's Bay Regional Council (HBRC) and Department of Conservation (DOC) for biodiversity values. Previously this wetland was associated with the Waitangi Estuary wetland; hence it was not listed as a priority. Council decided it warranted a separate management plan as it covers a different river system to the Waitangi Estuary, and the Tukituki Estuary has accordingly been added to the priority list.
This non-statutory management plan has been prepared in accordance with HBRG wetland policy guidelines (Appendix 1) to guide the HBRC and the community through a five year wetland protection programme without compromising flood protection measures. The greater part of the area falls within the Coastal and Marine Area as defined in the Regional Coastal Plan. This plan is consistent with the statutory HBRC Regional Plan and Regional Coastal Plan. A further plan covering the following five years will plan for restoration and enhancement, maximising the potential of local community input.

The Ngaruroro River has a large proportion of its catchment in forest parks and the underlying geology in its headwaters is predominantly ash dominant. These catchment scale characteristics ensure the river has good water quality along most of its length during low flow periods.

DRAFT This report is the final report of the Sustainable Low Flow Project, initiated by the Hawkes
Bay Regional Council in 1995. The project had the specific tasks of re-assessing existing
Minimum Flows# on rivers and streams in the Hawke’s Bay region, and for the first time
defining sustainable volumes of river and stream flow available for allocation.
The report defines a sustainable approach to resource allocation by identifying the risks to the
environment and to stream users. The methodology is set against the policy background of
the Resource Management Act (1991) and the Regional Water Resources Plan (HBRC 1995).
The sustainable Allocatable Volume is defined as the difference between a management
