**Subject:** OIA Request - 2003 West Auckland Aerial Spraying Operations & Bio-Insecticide Dispersal Data

Dear Ministry for Primary Industries,
Under the Official Information Act 1982, I am formally requesting documentation and operational data regarding the aerial spraying and bio-insecticide dispersal programs conducted over the West Auckland region circa 2003.
To ensure clarity and to assist your team in locating the correct archival files, I have divided this request into three specific areas of operational data:
**1. West Auckland Regional Operations**
Please provide the overarching operational documents for the 2003 West Auckland aerial spraying program, specifically including:
* The complete regional flight path maps for all low-altitude dispersal flights conducted during the 2003 calendar year.
* The formal schedule and logged dates of all aerial spraying operations executed over the West Auckland region during this period.
* The government's stated objectives and operational parameters for targeting this specific geographic zone.
**2. Kelston Airspace & Targeted Localized Data**
In addition to the regional data, I require highly localized operational logs for the suburb of Kelston. Please provide:
* The specific flight paths, altitudes, and spray logs for the airspace directly above and immediately surrounding the residential address of 6 Kelkirk Street, Kelston, during the 2003 operations.
* The precise dates and times that aerial dispersal occurred directly over or adjacent to this specific Kelston address.
**3. Bio-Insecticide Composition and Drift Modeling**
To accurately understand the environmental reality of these operations, please provide:
* The exact chemical and biological composition (including all active agents, inert ingredients, and adjuvants) of the bio-insecticide(s) utilized during the 2003 West Auckland operations.
* The environmental drift models or dispersal radius calculations utilized by the Ministry to predict how the bio-insecticides would settle into residential zones, specifically within the Kelston area.
As this request is being managed via the FYI.org.nz platform, I look forward to your acknowledgment of this request and receiving the information within the statutory 20 working days.
If any part of this request requires clarification to expedite the retrieval of these archives, please let me know.

Yours sincerely,
Cher Heather Ryker
