New Zealand's central bank says its systems have been hacked

Bank gave no indication of whether another government or a criminal organisation might be behind attack

New Zealand's central bank says that one of its data systems has been breached by an unidentified hacker who potentially accessed commercially and personally sensitive information.

A third-party file sharing service used by the Reserve Bank of New Zealand to share and store sensitive information was illegally accessed, the Wellington-based bank said in a statement.
