Defence Minister Jonathan Coleman has joked at the Pentagon that New Zealand has nothing to worry about when it comes to the US spying on its allies. Dr Coleman's comment was made during a press conference with his US counterpart Chuck Hagel which confirmed the two countries would resume bilateral military cooperation after a near 30-year interruption. The United States has been embroiled in controversy over surveillance by the NSA - the most recent revelations have centred on claims the agency bugged the mobile phone of German Chancellor Angela Merkel and 34 other leaders.
