Earlier this month, Blair Mason was sitting with five friends at a table in the communal space inside the mall when they were approached by a security guard and asked to leave.
Asked why they were being "kicked out", the security guard said they were disturbing the peace and intimidating adult shoppers.
"He said I was verbally trespassed."
The Kings High School year 10 pupil denied he and his friends were misbehaving, but conceded he had also been trespassed from another mall.
Blair believed he was trespassed because of his age and baggy clothing - not because of behaviour.
"We are just normal kids."
He said he had witnessed other youths being asked to leave the mall, and questioned whether the Dunedin City Council-development wanted their patronage.
"I thought it was a mall where you could hang around and buy something occasionally... I guess I was wrong."
Blair said he had written to the council to complain about his treatment and seek a reverse of the trespass.
Council city property assistant manager Rhonda Abercrombie said the council would respond to his letter in due course.
She confirmed Wall Street management had been having "trouble with certain youths" and shoppers and store owners had complained. It was unclear if Blair was one of the youths in question.
"We are not prepared to get into a situation of 'he said, she said'."
Since the mall opened in March, several people had been asked to leave, but no-one had been issued with a formal trespass notice.
When asked if staff were heavy-handed, Mrs Abercrombie said "our staff are pretty tolerant".
"We are conscious of keeping it a pleasant place to visit."
