Embarrassing errors in basic information supplied by the GCSB spy agency to Parliament have given Labour and the Greens fresh ammunition to back their call for a full inquiry into all of New Zealand's spy agencies.
Greens co-leader Russel Norman said the information was "bread and butter stuff".
"They should not be getting this sort of thing wrong."
Labour leader David Cunliffe said the blunder would "do nothing to reassure Kiwis their spy agencies are competent".
The Government Communications Security Bureau tabled a correction in Parliament yesterday to the annual report which contained a basic error in the number of interception warrants (for bugging phones) and access authorisations (for watching computers) issued and in force in 2012-13.
