Author Nicky Hager has confirmed the police raided his home last week in a bid to uncover the identity of the person who provided information used in his book Dirty Politics.
A Wellington police spokesperson said the raid last Thursday was part of investigations into the alleged hacking of emails belonging to Whaleoil blogger Cameron Slater.
The emails formed the basis of Dirty Politics, which Hager released early in the election campaign.
Hager told Radio New Zealand that five police spent 10 hours searching his home and removing property, including papers and electronic equipment, including computers, drives, phones, CDs, an iPod and a camera. However, he was confident the officers took nothing which would help their investigation.
