The north end of the bridge on Gayhurst Road. During the earthquake, the bridge was forced about 15 centimetres towards the river, the land falling away under the road. Fencing has been placed around the footpath, and the road filled and resealed so that it can still be used by traffic.

Damage to the Gayhurst Road bridge. The road has buckled due to the bridge's movement, and the bridge is cordoned off. Liquefaction covers part of the street, and in the background St Paul's Church is also cordoned off.

This report provided information on the location and character of the Ostler Fault Zone near Twizel. The fault traces, and associated recommended fault avoidance zones, were mapped in detail for inclusion in a District Plan Change for the Twizel area. The Ostler Fault Zone was mapped in detail because of the higher likelihood of movement on that fault than others in the district, and the potential for future development across the fault zone because of its proximity to Twizel. See Object Overview for background and usage information. The report recommended that the information be incorporated into the District Plan Change and that site-specific investigations be undertaken before development is allowed within the fault avoidance zones. These recommendations were taken up by Mackenzie District Council.

This report provides information on the locations and character of active geological faults and folds in Mackenzie District. The faults are mapped at a district scale and the information is intended to highlight areas where there is a risk of fault movement, and where more detailed investigations should be done if development is proposed in that area(depending on the potential activity of the fault and the type of development proposed). Most of the faults and folds identified at the ground surface in Mackenzie District are in rural or very sparsely populated areas. In addition, most of the faults have relatively long recurrence intervals (long-term average time between fault movements) in the order of several thousand years. Following the Ministry for the Environment Active Fault Guidelines, normal residential development would be allowed on or near faults with recurrence intervals this long. There are no recommendations associated with this report. The information in the report will be reviewed as required, after the remaining district reports are completed in the region. See Object Overview for background and usage information.
