A report which found that New Zealand's intelligence agency had "arguably" not broken the law has been met by derision by Opposition MPs who insisted on an independent, transparent inquiry.
An investigation led by Inspector-General of Intelligence and Security Paul Neazor cleared the Government Communications Security Bureau of illegal spying on New Zealanders.
Mr Neazor was asked to conduct an inquiry into potential breaches of the GCSB Act after Cabinet Secretary Rebecca Kitteridge's report on the bureau's compliance with legislation raised concerns about 88 instances where the GCSB had spied on New Zealanders.
The report was not made public, but GCSB Director Ian Fletcher said in a statement: "The Inspector-General formed a view that there have been no breaches, although the law is unclear and the Inspector-General recommends amending it."
Labour Party leader David Shearer said the findings would not restore New Zealanders' confidence in the agency.
