Police is seeking information on the whereabouts of Alexander, who is missing in the Waiatarua area.
The 15-year-old was reported missing to Police at about 8.30pm on Monday night, after he failed to return home from school.
Alexander was dropped off at Henderson High School where he was last seen at about 8.15am on 16 June.
Police have since established he did not attend school that day.
Enquiries have been underway since Monday evening into his movements, and Police is now issuing a public appeal.
Police believe that since Alexander was last seen, he has returned to his home address in Oratia and taken camping equipment and other necessities.
Alexander did not show up to a planned meeting with friends on Monday night.
Search and Rescue staff are deploying to carry out searching around parts of Waiatarua where he frequents.
Alexander is an avid outdoor adventurer and loves spending time in the bush.
It is out of character for him to not return home or let his family know of his whereabouts.
Police and Alexander’s family have concerns for his welfare.
Alexander is described as 180 centimetres tall, of medium build with light brown straight hair.
Anyone with information about Alexander’s whereabouts is asked to contact Police immediately on 111.
People can also update Police online or call 105 using the reference number 250616/4732.
