The last time Judith Collins' Twitter account fell silent was during the trip to China on which she visited Oravida's offices and dined with its chief executive and a Chinese official.
The Chinese Government's ban on Twitter meant her tweets were scarce. Now it has fallen silent again, after Ms Collins deemed Twitter was "not a good space to be" after the fallout from that trip to China.
Her retreat came as a relief to the Prime Minister, who said Twitter was "one of the big factors" that pushed Ms Collins into the state she was in and resulted in him sending her on leave. "There's a lot of trolls and bottom-feeders on that. In the end they get in people's heads ... it's a form of cyber bullying."
It is not the first time he has been asked about Ms Collins' use of Twitter. In February, a tweet about Green Party co-leader Metiria Turei's jackets being "vile, ugly and wrong" escalated into a much larger brawl. The Prime Minister said he would not rein her in: "I think she takes a lot of flak but I think she can give quite a bit as well, that's the nature of the beast."
Ms Collins' sometimes aggressive approach led to claims that the minister responsible for the anti-cyberbullying law was verging on it herself.
