On Friday, a police operation in the Ōtūmoetai area was expected to cause traffic delays for parents picking up children from schools.
Letters sent to parents from Ōtūmoetai Intermediate and Ōtūmoetai College said police were conducting an operation.
A police spokesperson confirmed the operation “appeared to be a pre-planned search warrant”.
Letters to parents say congestion is expected around Waihī, Ōtūmoetai and Cambridge Rds.
