The warehouse is at Auckland Airport, but is separate to the airport terminals and is not a public area.
“There is no threat to the public, and staff working in the warehouse have cleared the building while the Defence Force responds,” police said in a statement.
Access to the airport is not affected, however some roads near the warehouse are blocked.
An Auckland Airport spokesperson was unable to detail the nature of the unfolding incident but said there was no operational impact on flight arrivals or departures at either terminal this morning.
Auckland Transport updated its advisory at 9.20am saying some bus stops that were once closed were operational once more. However its AIR Link service would continue to take a detour until further notice.
