This is an experiment. We've coded large swathes of New Zealand's legislation, regulation, and some government policy into rules that run in the Open Fisca calculation engine. We've released all the code here, for anyone to use.
An instance of Open Fisca is running at https://rac.g0v.nz/
Supported platforms:
- GNU/Linux distributions (in particular Debian and Ubuntu);
- Mac OS X;
- Microsoft Windows (we recommend using ConEmu instead of the default console).
Other OS should work if they can execute Python and NumPy.
Pick option (A) or (B)
Follow this installation if you wish to:
- run calculations on a large population;
- run your own instance of OpenFisca-Aotearoa
- run your own instance of the OpenFisca-Aotearoa rules package, as an OpenFisca Web API.
- not modify the rules
There are 3 documented ways to do this - Pick your tech:
- Run in docker to run on an instance or your laptop
- Setup pew and install from pip to manage virtualenvs
- Run on heroku's PaaS cloud
Follow this tutorial if you wish to change the OpenFisca-Aotearoa rules or contribute to the source code.

pyenv is simular to rbenv/rvm (for ruby) and nvm (for nodejs).
