A fresh inquiry into our electronic surveillance service is being launched with the intelligence watchdog trying to find out if it actually makes good decisions about who to spy on - and how it stays politically neutral.
Inspector General of Intelligence and Security Cheryl Gwyn linked the inquiry to claims the GCSB spied on foreign diplomats competing against Trade Minister Tim Groser for the job of director-general of the World Trade Organisation.
However, she said it was unlikely she was going to be able to probe the allegations.
Instead, she said the inquiry would study the way the GCSB chose its targets, what its decision-making process was and how it stuck to its duty to be neutral in cases where there might be political advantage.
The Groser claims were among a string of stories broken by the Herald in a collaborative reporting project with investigative journalist Nicky Hager and The Intercept, the US news site with access to the trove of secret documents obtained by intelligence whistleblower Edward Snowden.
