The New Lynn train station in west Auckland was temporarily closed on Thursday mornig as police investigated a threat.
Auckland Transport told Newshub the threat was centred on Totara Ave, which runs by the station, but not the station itself, but in a tweet said it was at the station.
Posts on social media reported there was a "big bang" heard following the arrival of a police bomb squad.
Buses were told to stay away from the bus stop behind the station on Clark St.
"Bus operators will accept the rail tickets on Western Line till further notice," Auckland Transport said.
Just after 9am, Auckland Transport said the incident was "resolved" and normal services had resumed.
