Raraunga tuwhera

Open data is data that can be freely used, re-used and redistributed by anyone - subject only, at most, to the requirement to attribute and sharealike.

The key point is that when opening up data, the focus is on non-personal data, that is, data which does not contain information about specific individuals.

Pai tonu?

When released in its raw form, data is not open to the public in any meaningful sense. It is only open to a small elite of technical specialists (and those who can afford to hire them) who know how to interpret and use it.


It's only open, if it's open all the way down.

The Investment Approach to Justice: Taking Integrated Offender Management to Police, Justice and the wider social sector - Tim Hughes Principal Adviser, Ministry of Justice

These life-course risk models will be built on the Integrated Data Infrastructure at Statistics NZ. This powerful database hosts a very wide range of anonymised information about all New Zealanders, including records about tax, earnings and employment records, health, education, and welfare receipt. We will use factors such as age, and early CYF involvement, to predict future offending and victimisation for the resident population of New Zealand.

Tētahi atu raru ki tai

Individuals in general experience the dispossession of their data, but marginalized persons and groups experience additional ways in which their data is “colonized” and used to further discriminate against them.

Can we get past these problems?

Power based analysis

Maximise autonomy by keeping data private (mana motuhake)


While maximising control over the state by being able to see the data they are using


Very simplistically

View it through the lens of the power differential, those with the power should be open, those without, not so much.

We are used to asking:

  • What do we do with all these data?
  • How do we catalogue them?
  • How should we use them?


Less often we consider the questions:

  • Should we collect, aggregate, catalogue and exploit these data?
  • If so, how?
  • What would be ethical means for doing so?

Nā reira

Data can be good, or bad, and used for good or bad

Open data makes bad data worse, and good data better (maybe)


Be very careful, once released under an open license you can never unrelease it.
