David Laing PublicSeen by 156And which agency can provide it?
Note that some interesting health data and hacks may come out of this event the weekend beforehand: http://www.hinz.org.nz/?page=2015HackathonWLGTN
The Ministry of Health's data page lists what they currently provide, and they also list on data.govt.nz. Other agencies may also hold data relevant to public health outcomes, in particular district health boards.
