DISAGGREGATED class 4 gaming machine profits (GMP) data

I am currently using the class 4 gaming machine profits (GMP) data: Currently, the publicly available version of this data is aggregated to the Territorial Authority (TA) level. I would like to request access to the original disaggregated GMP data, at the venue level, per quarter. I would like to request this data for the time period from 2004q1 to 2021q2.

What factors increase or decrease class 4 GMP at a particular venue? Does the number of machines matter? Does the number of venues nearby matter? Does the corporate society matter? Does the number of jackpots matter? Does the local social deprivation index matter?

These are especially important questions given my initial finding: Class 4 GMP per capita (adjusted for inflation) in NZ has been falling steadily since the implementation of sinking lid and cap policies by local councils. But it has stopped falling since 2014 and has been steady since. Why? Disaggregated data will allow us to tell a rich, nuanced story on a very important topic with wide-ranging impact.

Research into the factors that cause gaming machine proceeds per capita to fall, or not, will help evaluate and guide policies in the regulation of class 4 gambling. Part of the role of the regular (Department of Internal Affairs) is to minimise harm caused by gambling, which is strongly correlated with GMP. The Ministry of Health is also concerned with minimising problem gambling.

I am an academic researcher in the AUT School of Economics, trained in Econometrics and Applied Microeconomics. I am a user of the StatsNZ IDI (Integrated Data Infrastructure) and have gone through their confidentiality training. I understand that you might not want to release the disaggregated GMP data to the public due to confidentiality reasons, but I am willing to sign a non-disclosure agreement if need be so to have access to this data confidentially.
