Dear Mike,
Clarification requested re: Official Information Request for Information on Research into
Methamphetamine Contamination in Carpet
I refer to your official information request received by the New Zealand Institute for Public
Health and Forensic Science dated Wednesday 17 June for the following information:
“Please provide information on any research, reports, results and communications (both
internally and externally) into methamphetamine contamination research projects, started,
completed and/or underway into methamphetamine contamination?
Please provide information on any research, reports, results and communications (both
internally and externally) into contamination research projects, started, completed and/or
underway into carpet and/or other furnishings?
Please include
a. Start date.
b. Anticipated completion date.
c. Current project status.
d. Work completed to date.
e. Preliminary findings or interim conclusions.
f. Progress reports supplied to HUD or any other government agency.
g. Terms of Reference or Methodology used in the research
h. Project objectives”
We note that the subject line of your email refers specifically to “
information in relation to
methamphetamine contamination in carpets”. However, in the body of the email, you have
also requested “
research, reports, results and communications” for research projects relating
to methamphetamine contamination in general. This broader aspect of your request is very
wide in scope and would require a substantial amount of time and resources to process. In
order for PHF Science to provide a response within a reasonable timeframe we invite you to
clarify or amend the scope of your request to focus on research projects in relation to
methamphetamine in carpets and/or furnishings.
Please note, any clarification or amendment of a request is considered to be a new request for
the purpose of calculating the maximum statutory timeframe for response—see section
(15(1AA) of the Official Information Act 1982).

It would be appreciated if you could confirm your clarification or amendment of the request
via return email. Once your confirmation is received, the request will be actioned.
Yours sincerely
Wendy Chung
PHF Science Legal Coordinator
