Auckland's Myers Park is fully open to the public again after Sunday night's police shooting.

Investigators have finished their examination of the scene.

Auckland Police Commander Richard Chambers says he's not yet in a position to reveal details of what evidence was found at the scene.

He says before he can do that, interviews with key witnesses need to be completed.

Three investigations are underway into the shooting of David Cerven after he called police to the park, saying he was the man responsible for a number of North Shore armed robberies.
