"The barriers were down, the lights were going and the train was honking but he was too slow."
Curry-Black said upset friends and family had gathered at the scene and the body had been covered by a sheet.
A police spokeswoman said the death was believed to be accidental and officers were making inquiries.
At 6pm Auckland Transport said train services had returned to normal after buses were used as replacement services while police worked at the scene.
The death comes just weeks after national Rail Safety Week aimed to remind people to stay alert at level crossings and near train tracks.
Between 2010 and 2015 there were 900 collisions or near-collisions with people and vehicles at level crossings.
