Four Whanganui schools were in lockdown after a man wearing a balaclava was seen carrying a gun this morning.
Streets in the suburb of Tawhero were under police cordon after the man was spotted just before 8am on Friday.
The lockdown and cordons were lifted about 9.15am after police searched the area and found nothing of concern.
A police spokeswoman said Tawhero, St Marcellin and Rutherford Junior High Schools and the Pasifika Learning Centre were all in lockdown.
