EQC have changed their TC3 Drilling Plan FAQ (here) by adding more text and altering the schedules for the start and finish of drilling in various suburbs.
The latest timetable changes indicate completion dates have been extended out for many suburbs.
Also added is a small amount of information on the repair timeframe. For those sitting very close to the cap the underlined the words may be relevant to your situation.
Repair timeframe: Once drilling results are analysed and a repair method agreed your EQC claim may exceed the maximum EQC entitlement. If this occurs you will be “paid the cap” and your repair/rebuild will be managed by your private insurer.
If your claim remains under the EQC cap your home will be repaired within the Canterbury Home Repair Programme (managed by Fletcher EQR). The Canterbury Home Repair Programme commits to repair of all homes with damage between $50,000 and $100,000 in value by December 2013 and all homes with damage between $15,000 and $50,000 by the end of 2015.
There is also a small section on foundation repairs:
The repair or rebuild of your foundations must meet Building and Housing standards guidelines and may require a building consent. A structural engineer will design your home's foundations if a building consent is required. This work comes under your building claim.
