1. The original decision to remove the fields in 2016
I request the correspondence and documents regarding any and all decisions pertaining to the 2016 change to the open data csv files regarding not publishing "Grey" data items in the revised Open Data, [with respect to those data that were produced in the existing Open Data CSV files before that time].

I request the correspondence and documents regarding the review and assessment of "Grey" data items, and the decision to not include them in the Open Data in 2018/2019

3. Complaints about Grey data items by the public prior to 2016
I request the number of Correspondence from the public to NZTA complaining about confidentiality in Crash Open Data prior to 2016 that pertained to those Grey data items that were removed. These should be grouped by year and reason stated
