distribution" admitted to in Footnote 3 (page 3, Appendix 1).

2. Confirmation of Non-Adjustment: 
If no mathematical weighting or demographic corrections were applied to
this "unreliable" clinic-attendance sample before it was used to justify a
Section 5 NZBORA human rights breach, please confirm this in writing.

Please provide all internal memos, risk assessments, or briefings provided
to the Director-General discussing the "unreliability" of the 2022
dataset.

Please provide the specific "margin of error" the Ministry accepted when
using this clinic-attendance sample to calculate the "proportionality"  of
the 14 directions.

5. Broken Evidentiary Link:

Limitations of the Data at
