Here is the link to the MBIE Cash Settlement booklet recently released via an OIA request.  It was prepared by MBIE and CERA with input from EQC, CCC and Worksafe.  It is an excellent handbook for homeowners and contains accurate advice as to what to do when considering a cash settlement.  It makes many useful suggestions as to information to ask of the EQC/Insurer before settling and also what ought to be included in the cash settlement calculation.  Still a useful resource.
