NRC is responsible for monitoring compliance with resource consents and rules in Regional Plans. Activities monitored in relation to groundwater include groundwater abstraction and bore construction.
The Council maintains a bore log database that incorporates all bore logs provided by drillers. There are in excess of 4600 bores registered on the database, 131 of which were registered during 2007-08.
All bores installed under a bore permit (resource consent) are visited by NRC monitoring staff to ensure that they comply with the conditions of their consent. During 2007-08, 66 consented bores were inspected by NRC staff and 25% were found to have minor non-compliance. These minor non-compliances included bores lacking a concrete pad, or removable cap and access point where water level readings can be taken.
The photographs below show a poorly constructed and maintained bore (left) and the correct construction of a bore (right) including a concrete pad, 30 cm high casing and removable cap.

Formal enforcement action for significant non-compliance was taken on three occasions during 2007-08, with regard to non-compliant bore construction.
Compliance monitoring of resource consents issued for groundwater take continued during 2007-08. There were no cases of significant non-compliance and no formal enforcement action was taken during this financial year.
