Waikato DHB chief executive Dr Nigel Murray has launched an external review after two patients absconded from a mental health facility this week.

Benjamin Thomas Manuel, 28, and Morgan Hamiora-Smith, 21, were reported absent without leave from Hamilton's Henry Rongomau Bennett Centre on Selwyn St on Monday, at 9.23pm.

The two men have now been located by police after they were brought in to the Coromandel Police Station by a relative at about 9.30am this morning.

"The 28 and 21-year-olds had been on the run since absconding from the facility on Hamilton's Selwyn St about 9pm on Monday.

"As a result of appeals for sightings of the pair Police received several calls from members of the public and they were identified as being in the Kennedy Bay area.

"The priority now for police is getting the pair assessed and assigned the appropriate level of care required."

Waikato DHB chief executive Dr Nigel Murray says the aided police's search by providing everything they knew about the men and also made a senior psychiatrist available to them.

'I intend to launch an external review of our service immediately. The public has every right to expect we provide the best service we can for our patients.”

The pair were able to get through a security door into the courtyard of the medium security rehabilitation unit and used outdoor furniture to scale the external fence.

They were last seen running down Selwyn St by a member of the public who contacted the police. At about the same time staff reported the two patients as missing and also alerted the police.
