That the bureau has the capacity to collect information from a variety of sources is no secret; the challenge has always been to crack the technologies where this intelligence might sit.
I don't doubt that New Zealand's intelligence agencies could have a similar capacity to collect information and data as the American National Security Agency, but we must remember our agencies will continue to have limited budgets and, more importantly, limited need to target anyone in this country other than those whom they deem absolutely necessary to surveil.
Spying is intrusive and it is important to make sure there is absolute justification in what is being requested when a Security Intelligence Service officer or a police representative lawfully seeks a warrant for the purposes of intercepting the communications of a New Zealander.
And that does not mean that GCSB will just ask its American and British counterparts to collect on their behalf.
The bureau continues to be acutely aware of what it can and cannot do. The same applies to our law enforcement people; they know there is always a line that cannot be crossed, and we see more and more that those who do cross this line are removed from these agencies.
Let us not forget that at least one individual deemed responsible for the state in which Rebecca Kitteridge found the bureau late last year, was removed shortly thereafter.
This was something of an ignominious departure after a lengthy career of service to your country, but when it comes to accountability, nobody - and certainly no one within the intelligence services - should be immune from such consequences.
The Inspector-General's investigation into the possibility more than 80 New Zealanders were "illegally spied on" by the bureau determined the accusations unfounded, and there remains no suggestion that any individuals within GCSB deliberately ignored or circumvented official legal advice.
Those who believe the proposed amendments to the GCSB legislation give the agency carte blanche to spy on us whenever they so desire are wrong. It does not. The purpose of the amendments is to provide a clear and unambiguous statutory framework from which the bureau can effectively, and most importantly, legally, operate. Nothing more, nothing less.
The revised legislation also calls for exemptions from the Privacy Act for the GCSB; more common sense and in no way a bad thing. Further legislative updates will take place in respect of the Inspector-General of Intelligence and Security and Parliament's intelligence and security committee oversight mechanism.
Again, efforts by the Government to make oversight more robust and credible are necessary; no longer can this system of checks and oversight be seen as a "rubber-stamping" exercise. It must have bite.
The current legislation is loose and does not reflect realities the state faces. So let the Government clean up the GCSB's act. And then let us revamp the oversight capability so that it has real teeth.
