"Mindful of the importance of being useful", GCSB Director Ian Fletcher offered the GCSB's services to Tim Groser.
When information about the GCSB spying on Tim Groser´s competitors for the job of Director of the WTO became public in 2015, the general assumption was that this was a case of the government leaning on a supposedly politically neutral agency to advance its agenda.
Instead, what the IGIS´s report portraits is an agency taking it onto itself to do some extra-curricular spying in order to be in the good books with the government.
The report by Inspector General Cheryl Gwyn is similar to Ian Fletcher´s memory - very specific in some details, but extremely vague in others. It states that it was Ian Fletcher´s idea to approach Tim Groser and offer him some extra spying to help him get the top job at the WTO. The report explains this by Fletcher being "mindful of the importance of being useful", i.e. he wanted to lick Groser´s boots, possibly because there was some public concern about his appointment (he had been appointed by personal recommendation from the PM, somewhat bypassing the usual selection process).
