Notification of Extension

 

This email is to notify you that the Ministry is extending the 20 working
days available to it to respond to your Official Information Act 1982 (the
Act) request pursuant to section 15A(1)(b) of the Act. 

 

We require an additional 16 working days as “consultations necessary to
make a decision on the request are such that a proper response to the
request cannot reasonably be made within the original time limit”.

 

You may now expect a full response to your request by 29 May 2026.
However, we will endeavour to respond to your request as soon as
practicable before this date.

 

Notification of Partial Transfer

 

Part of the information to which your request relates – namely points 2
and 4c copied below – is more closely connected with the functions of
Earth Sciences New Zealand (previously NIWA).

 

“Copies of any documents held from 1 January 2015 to present that:

               2.            Evaluate or discuss:

               •             aerosol–cloud interactions

               •             cloud condensation nuclei (CCN)

               •             cloud formation or reflectivity

               •             rainfall or precipitation effects

               4.            Include any modelling, monitoring, or
scientific assessments of:

               •             observable “ship track” phenomena”

 

 

In these circumstances, we are required by section 14 of the Act to
transfer your request.

 

Accordingly, parts 2 and 4c of your request are being transferred to Earth
Sciences New Zealand today. You will hear further from them in due course.

 

Please note you have the right under section 28(3) of the Act to approach
the Ombudsman about this extension.

I am writing to acknowledge receipt of the transferred request. In
accordance with the Official Information Act, we will be responding to
this request by 5 June, which is within 20 working days. We also wish to

process, please feel free to get in touch.
