Your Official Information Act request, reference: GOV-009516
Thank you for your email of 2 March 2021, asking for the fol owing information under the Official
Information Act 1982 (the Act):

•  The Public Confidence Statistics and Results pertinent to the ACC January 2020 to date
•  The Public Confidence Statistics and Results pertinent to the ACC for the Individual years 2005 to
2019
•  Please include a copy of the format of questions
•  Please Disclose any Formulas or Algorithm technics used to target any particular group of
Claimant invited to take part in The Public Confidence Surveys

Public confidence statistics since 2005
The appendix below provides the quarterly public trust and confidence scores since 2005.

Please note that since 2014, ACC have been publishing these in the Annual Report, and since 2018 in the
quarterly reports. You can find copies of these on the ACC website at www.acc.co.nz.

In 2016/17 we changed the way we reported our statistics in the annual report, to provide public trust
percentages as an annualised mean of the quarterly statistics. Prior to 2016/17, the results published
represented the most recent quarterly results, as a single and current score.

Methodology of survey

Public trust and confidence in ACC is measured via an Omnibus survey conducted by Research New
Zealand. Quarterly, 500 adult New Zealanders, 18 years of age and over, are randomly sampled via
telephone interviewing. Quotas are set to ensure the sampling provides a representative sample of New
Zealand. Respondents who report knowing a reasonable amount about ACC are asked whether or not
they have ful  trust and confidence in ACC (‘yes’ or ‘no’). The trust and confidence KPI reflect the percent
that respond ‘yes’. Annualised results are subject to an approximate margin of error of plus/minus 3.0
percent (at the 95 percent confidence level).

Format of questions
Research New Zealand use the fol owing format for the Omnibus survey on government agencies:

1.  Awareness - Unprompted: Now I’d now like to ask you some questions about government
departments and agencies. You may not have had any direct dealings with them. It’s your
opinions and views that we’re most interested in. First of all, can you tell me the names of all
the government departments and agencies you are aware of? Any Others?

2.  Knowledge (Based on respondents who are aware of ACC): I’m now going to read a list of
government departments and agencies. For each, please tell me whether you feel you know a
reasonable amount about what they do.

GOV-009516

3.  Trust & Confidence (Based on respondents who have a reasonable amount of knowledge
about what ACC does): Thinking about government departments again, would you say you
have full trust and confidence in these particular departments and agencies? Just give me a
‘yes’ or a ‘no’.

We are unable to provide information on specific algorithms or formulas
No algorithms or formulas are used to target any particular group. We use random sampling
representative of the New Zealand population when carrying out the survey. For this reason, we are
refusing this part of your request, under section 18(e) of the Act, as the information does not exist.

[email address].

If you are not happy with this response, you have the right to make a complaint to the Ombudsman.
