To: enquiriesSubject: Geo-locations of polling stations

Hello,

I am writing to inquire whether it would be possible to obtain a copy of the geographic coordinates of polling stations.

I am keen to map of the results of the last general election at the level of the individual polling stations. I see that the http://www.electionresults.govt.nz website publishes the addresses of polling stations. Is this information available in a format that can be used in a GIS (e.g. shapefile) so that it can be mapped. Alternatively, a table of the stations and their latitude, longitude would be fantastic.

Please let me know if this is possible.

All the best,
Chris McDowall

Subject: Geo-locations of polling stations

Kia ora,

Thank you for your enquiry regarding geographic locations of polling places.

Attached you will find a tab separated data file. The file contains name, address, location, meshblock and accessibility data for the physical polling places used at the 2008 general election. Geographic locations are given as Eastings and Northings in the recently superseded New Zealand map grid.

The file does not contain locations of advance voting facilities or electorate-level “virtual polling places” for advance votes, special votes, polling places where less than 6 votes at were taken or votes allowed for Party Vote Only. We cannot provide vote data for these virtual polling places at any level of detail finer than the whole-electorate level.

The data are as used internally at the 2008 general election. This is the best available information, but should not be considered 100% complete or correct. You will note that a few locations and many meshblocks are missing from the data.

I hope this satisfies your requirements.

Is there a relationship between votingpatterns and socio-economic deprivation?
