The Twitter account used to drip-feed information taken from the computer of the WhaleOil blogger has been suspended.
Blogger Cameron Slater, who has complained to police about the hacking, tweeted: "And @whaledump is dead...good job."
The account has been used over recent weeks, apparently by the hacker "Rawshark", to drip-feed information aimed at backing up claims in Nicky Hager's book Dirty Politics.
This week the hacker began releasing information which purported to be social media conversations between former Cabinet minister Judith Collins and Slater.
The pair had called the transcripts "forgeries", which Rawshark denied.
The account, at the time it was suspended, had more than 9000 followers, overtaking WhaleOil's 7700 in just a few weeks.
Comment was being sought from Twitter.
