Cordons are being lifted.
A large number of police were at the scene as they attempt to safely resolve the situation and cordons were in place around the address as a precaution, a police media spokesperson said.
Henderson Valley Rd between Great North Rd and Smythe Rd is closed and detours are in place. Buses on routes 141 and 142 are also taking a different route while the operation is under way.
The cordoned-off property is opposite Auckland Council Henderson Service Centre.
A motorist told the Herald traffic was at a standstill on Great North Rd with between 40 and 50 cars stopped as they tried to turn right onto the closed Henderson Valley Rd.
