Police have given Papakura residents an early wake-up call, sending an armed offenders squad to raid a property at 5:35am.
Great South Road was cordoned off from Rosehill Drive to Settlement Rd as the search warrant was carried out on Friday morning.
It is not known whether any arrests were made.
Diversions were put in place, and have since been lifted.
Police say they'll give more information on the search warrant later in the morning.
