The navy is urgently reviewing security after a man stole ammunition, flares and smoke bombs in a depot break-in on Auckland's North Shore at the weekend.
The Kauri Pt ammunition depot is manned 24 hours a day but the burglary was not noticed until Monday morning, the navy said.
A 25-year-old man was to appear in North Shore District Court yesterday on a charge of burglary.
Changes had already been made to security at the depot, in the suburb of Chatswood, but the navy would not reveal details.
A review of security and processes would be done before any decision on whether anyone would be disciplined over the break in.
Detective Sergeant James Watson said police had recovered all the ammunition. No weapons or explosives were stolen.
