The NZDF has increased its security alert level from Ringfence White to Ringfence Grey. The key is that the level of direct threat, while increased, remains non-specific. The responses to that threat level are therefore generally appropriate to Business as Usual (BAU) with a heightened level of awareness and deterrence.
For non-members of the NZDF you will not be able to enter the Naval Base unless the Main Gate has been advised of your proposed visit. I am not sure how this will effect visitors attending funerals but watch this space.
