Request for information 
Thank you for your Official Information Act 1982 (OIA) request of 6 September 2023, in 
which you requested: 
Could you please answer the fol owing questions with respect to covert human 
intel igence sources (CHIS)? 
1. Between 2018 and 2022, how often was CHIS information used to disrupt
drug importations into New Zealand?
2. Between 2018 and 2022, how often was CHIS information used to disrupt
threats to life (e.g., terrorism) in New Zealand?
3. Between 2018 and 2022, how often was CHIS information used to seize
firearms that were being il egally possessed in New Zealand?
Please also provide a breakdown of these statistics by year within the ranges 
requested. 
I seek this information to make comparisons to similar data released in the UK: 
https://www.gov.uk/government/publications/covert-human-intel igence-sources-
draft-code-of-practice/covert-human-intelligence-sources-bill-factsheet-
accessible-version. 
I would note that statute in the United Kingdom (UK) is different to New Zealand. The 
article in the link you provide for comparison deals with a Bill (Covert Human Intel igence 
Sources Bil ) that amended legislation in the UK that has no New Zealand comparison. 
Unlike the UK, in New Zealand there are no circumstances where Covert Human 
Intel igence Sources (CHIS) are authorised to commit criminal activity, as is the case in 
the link provided. 
Information relating to Police informants is sensitive information. If Police was to release 
specific details about cases, that would provide the opportunity for criminals to identify 
CHIS, which puts them at risk. CHIS are reliant on Police to maintain their confidentiality, 
and this includes ensuring the content of their information is protected so as their 
identities are not able to be established. To release the information you have requested 


would risk identifying CHIS, which could put them in danger and also reduce Police’s 
ability to investigate cases. Your request is therefore refused pursuant to the following 
sections of the OIA: 
•  6(c) – the making available of that information would be likely to prejudice the 
maintenance of the law, including the prevention, investigation, and detection of 
offences, and the right to a fair trial 
•  6(d) - the making available of that information would be likely to endanger the 
safety of any person. 
You have the right to ask the Ombudsman to review my decision if you are not satisfied 
with the response to your request. Information about how to make a complaint is available 
at: www.ombudsman.parliament.nz. 
Yours sincerely
