Thank you for your email of 3 December 2025 requesting the following under the Official
Information Act 1982 (the Act) of the Ministry for the Environment (the Ministry):
Okay so just confirming - MFE has complaints going back to the early 2000's -
repeated denials that this practice are occurring yet no evidence to refute these
claims?
Please provide internal process documents MFE must follow when environmental
complaints are made
There is ample evidence to suggest the "environment" is being ruined by this practice
including but not limited to
- visual aspect of skies
- constant trails
- haze that blocks the sun
- the number of trees that are down across the country as the chemicals destroy there
root systems
- reduction in the number of bees that is being reported on
- zombie fish in Dargaville
- soil fertility
- Particulate matter and air quality
- Health issues
- Food quality
All of the above should be in MFE's remit however you fail to "investigate" despite
ample evidence from the public disclosing this is going on. Why do we fund you with
our taxes when you appear to be negligent in your duties?!
The Ministry does not carry out geoengineering activities and has no evidence that such
practices are occurring in New Zealand. Geoengineering is not recognised as an
environmental issue under New Zealand law, so it falls outside of the Ministry’s
responsibilities. We do not have a role in investigating such claims and do not hold any
internal process documents or information specific to geoengineering.
Under section 31 of the Environment Act 1986, the Ministry’s functions are primarily
advisory, including providing advice to the Minister for the Environment. The Environment
Act does not require the Ministry to investigate environmental complaints. Section 16 of the
Environment Act authorises the Parliamentary Commissioner for the Environment to

investigate matters that may adversely affect the environment and report findings to
Parliament.
While the Ministry does not have a process specific to geoengineering, we have general
processes for handling environmental complaints and concerns. Where concerns relate to
environmental activities regulated under the Resource Management Act 1991, these are
usually managed by local councils or, in some cases, the Environmental Protection
Authority. You can find more information in the fol owing resources:

Responses to similar previous requests are also published on the Ministry’s website:
https://environment.govt.nz/oia-releases/ You have the right to seek an investigation and review by the Office of the Ombudsman of
my decisions relating to this request, in accordance with section 28(3) of the Act. The
relevant details can be found at:
www.ombudsman.parliament.nz. Please note that due to the public interest in our work, the Ministry publishes responses to
requests for official information shortly after the response has been sent on our website at:

queries about this, please feel free to contact our Ministerial Services team at:
