INPUTS

Council Ratings Valuation (RV) data:

OUTPUTS

Four csv files (one for 2011, 2014, 2017 and 2021) with the following data fields added:

  1. Because titles can be cumbersome to work with, please add a unique numeric identifier for each RV in the dataset based on its certificate of title. Call it ‘FID_certificate_of_title’.

PROCEDURE FOR MATCHING RVs TO LINZ DATABASE
Use certificate of title to match each valuation to a LINZ parcel(s).

  1. Indicator for one-to-many matched LINZ parcels: ‘One_to_many_matched_parcels’
    a. Equal to one or zero
  2. Indicator for many-to-one matched LINZ parcel: ‘Many_to_one_matched_parcels’
    a. Equal to one or zero

Geocode the RV addresses and then follow the matching process detailed in Phase 1 for those that failed to match on title alone. Set LINZ_MATCH_CODE=0 for those that did.
