The Hawke's Bay Regional Council (HBRC) is responsible for maintaining flood protection infrastructure throughout the major braided river systems in the Heretaunga Plains. These include the Tukituki, Waipawa, Ngaruroro, Esk and Tutaekuri. Gravel extraction and beach raking from dry river bars are tools HBRC uses to maintain flood-flow capacity and reduce erosion of flood control infrastructure.

In this report we map active faults in the Wairoa District for the purposes of producing Fault
Avoidance Zones suitable for land-use planning. The faults with the highest rates of activity
in this district are in the west: the Waiohau, Whakatane, Waimana and Waiotahi faults
(Figure 1.1 and Figure 2.1). There are also several short traces of possible active faults in
the low hill country to the northeast of Wairoa township. Active faults in some parts of the
Wairoa District were previously mapped by Langridge et al. (2011) but in the five years since
that report, methodology for active fault attributing has slightly changed and new fault
mapping and interpretation for the western part of the Wairoa District (not covered by
Langridge et al., 2011) is available in the GNS Science 1:250 000 geological maps of
Hawke's Bay (Lee et al., 2011) and Rotorua (Leonard et al., 2010). This report updates the
active fault mapping the whole of the Wairoa District, including an update of the areas
covered by Langridge et al. (2011); it provides GIS data for active fault linework and Fault
Avoidance Zones in a manner consistent with recent work in Hastings District and Central
Hawkes Bay District (Langridge and Ries, 2014; 2015).

This Riverbed Gravel Review Summary provides a more succinct overview of the findings of the 12 issues
plus a riverbed gravel management plan identified in the 2010 scoping study by Tonkin & Taylor to
review the way in which HBRC currently manages riverbed and coastal gravel resources within Hawke's
Bay. The issues identified in the scoping study as requiring more research were examined over a 7-year
period with completion due at the end of the 2016/17 financial year. The work programme was
approved by Council in 2010 with funding provided by an increase in extraction management charges
(agreed by commercial extractors).
This summary also provides some updated material and comments since completion of the earlier
sections of work. This body of work contains the most up to date understanding of the issues around
riverbed gravel extraction, including sustainable supply, market demand, ecological effects of the
activity, flood management implications, legal, planning and financial implications.
It is this significant body of work and reports that provides the background for and informs the Riverbed
Gravel Management Strategy (RGMS). It is proposed that the recommendations of Sections 11 and 12
(EMS Report) be largely adopted and followed to complete the drafting of the RGMS.
