Today the New Zealand Herald is releasing an interactive visualisation which shows every candidate donation for last year's election.

We asked our readers to help us get the data out from over 400 returns with our Money in Politics crowdsourcing campaign.

Thanks to nearly 600 contributors, we were able to finish reviewing 2014 donations quickly.

Candidates who submitted "nil" donations are not included in the interactive, or the table.

We are halfway through the 2011 donations. When these are finished, we will be able to do a comparative analysis between the two elections.

We are now able to publish the data set obtained from this campaign. Readers can see the spreadsheet here, or download this file.

Each of these entries has been verified by the Herald data desk. If you have any queries, or issues with the data set, please get in touch.
