The Reserve Bank's abolishing its long-standing practice of releasing Official Cash Rate decisions on an embargoed basis to media and analysts after an independent investigation found a Newshub MediaWorks reporter leaked news of the March decision ahead of the embargo time.
RBNZ Governor Graeme Wheeler said the March 10 leak was "a serious and disappointing breach of many years of trust".
"It created the opportunity for improper gain on financial markets and damage to the integrity of the Bank’s communications."
Wheeler said that no evidence had emerged that the leak gave rise to any financial market impact.
MediaWorks chief executive Mark Weldon said his organisation "unreservedly apologises to the Reserve Bank for this incident".
"Once MediaWorks was aware a leak had taken place, it conducted its own investigation to determine whether the leak had come from within MediaWorks and self-reported that to the Reserve Bank."
MediaWorks acting chief news officer Richard Sutherland said the leak was caused "by a failure within News to follow proper process and changes have already been made as a result. We are addressing the breach with those concerned and new policies and training will be implemented moving forward."
An inquiry was launched by the RBNZ after Michael Reddell, a former senior economist at RBNZ, who now runs a blog, said he was emailed an hour before the OCR result was released on March 10 and told that the RBNZ was cutting rates.
Wheeler said he was "extremely disappointed" that the information was leaked initially and then communicated more widely.
“The fact that several people outside the Bank, who had access to the information improperly, failed to alert the Bank immediately, was irresponsible and left open a significant risk that the Bank could have closed down quickly with an immediate official release.”
After the reports that there may have been a leak the RBNZ had an independent investigation conducted by Deloitte's forensic unit.
The investigation found that, "contrary to the rules of the lock-up", information on the Bank’s decision to cut the OCR was transmitted by a Newshub MediaWorks reporter to several people in the Newshub office from the media lockup for the Monetary Policy Statement on March 10.
The RBNZ said this information was then passed on by another person in Newshub MediaWorks, "well before the MPS official release", to "an economics blogger".
"The blogger only alerted the Bank to the leak after the MPS was officially released," the RBNZ said.
Deloitte was assisted in its investigation by MediaWorks’ legal team, who undertook an internal investigation, uncovered emails that confirmed the leak, and reported these to Deloitte.
Following the investigation, the RBNZ said it would tighten its procedures for the release of confidential information. It will now discontinue embargoed lock-ups for news media and analysts ahead of announcements of interest rate decisions, Monetary Policy Statements and Financial Stability Reports.
Head of communications Mike Hannah said the RBNZ had considered alternative arrangements relating to information security. However, none completely mitigated the technology and "human risks".
“We have reviewed the procedures of several central banks. None provide lock-ups for analysts prior to major policy announcements, and the few that provide embargoed lock-ups for media representatives take extensive measures to control the media environment in the lock-up that are not viable for us. Most central banks do not provide embargoed lock-ups.”
Hannah said that from the April 28 OCR statement release, the RBNZ will issue OCR and MPS statements via its pages on Thomson Reuters and Bloomberg screens at 9:00am, as is currently the case, followed by release on its website and to email subscribers. In the case of the quarterly MPS and six-monthly Financial Stability Reports, the release of a news release and these documents at 9am will be followed an hour later by a press conference.
“The decision not to provide lock-ups for media or analysts means that these parties will receive the information at the same time as other financial market and public audiences.”
