Police are looking for information on the whereabouts of 62-year-old William Garland who was last seen at a Manurewa address on Saturday, May 2.

Mr Garland was wearing a white button up shirt, dark grey jeans and oversized shoes with no laces.

He walks with a shuffle and is likely to try and shake hands with people he sees.

He also has a distinctive tattoo of a spider on his nose.

Mr Garland requires daily medication and since he has not had it for four days, his condition may deteriorate.

Police have concerns for his safety and ask that anyone who may have seen him contact them on 111.
