Kia Ora,

Regarding the "Community water fluoridation: NZBORA analysis" published in November 2024, please provide the following information under the OIA:

1. The Statistical Formula:
Please provide the specific mathematical formula, weighting, or protocol used to correct the 2022 Community Oral Health Service data for the "unequal provision of dental services" and "uneven geographic 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.

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

4. The Accepted Margin of Error:
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:
Footnote 3 (page 3) directs the reader to a specific Discussion on the Limitations of the Data at https://www.ehinz.ac.nz/assets/Reports/O... This link is currently broken and returns a "404 Error." Please provide the full, original document that was intended to be reached by that link at the time the Director-General signed the November 2024 analysis.

Thank you for your time,

Alisha Riley
