The Dunedin secondary school's roll was capped at 1035 pupils in August last year, following a long-running dispute with the Ministry of Education about the school's rapidly growing roll.
The ministry requested an enrolment scheme be established at King's High School to ensure the network of schools across Dunedin was used well, in the interests of all pupils.
It aimed to share pupils with other Dunedin secondary schools, rather than build more classrooms at King's, which was at capacity.
Initially, the ministry told the school to establish an enrolment scheme by August 7 last year, and when the school vowed to fight any intervention, the ministry threatened to appoint a limited statutory manager to establish the scheme.
But as the deadline approached, both parties entered talks to resolve the situation.
Eventually, the school board of trustees agreed to introduce an enrolment scheme.
Under the terms of the agreement with the ministry, the enrolment scheme was to take effect officially next year, but if the school's roll exceeded the cap this year, it would be brought forward to apply in May this year.
The school's March roll return this year showed it had exceeded the agreed limit, with 1048 pupils enrolled, and it was required to fast-track its enrolment zone plans.
A proposed "home zone'' for the school was sent out for public consultation last month, and the deadline for feedback was May 6.
The school's board of trustees assessed the feedback and decided to forge ahead with the proposed enrolment scheme.
This week, it was approved by the Secretary for Education and is now in effect.
King's High School rector Dan Reddiex was pleased the situation with the school's roll had been resolved.
He believed the school's roll would not grow any further.
"What we've got moving forward is large numbers going through every single year level, so the roll is now essentially going to be pretty steady.''
Mr Reddiex said the proposed enrolment zone was not expected to have any impact on the school's year 9 enrolments for next year.
He said the danger with enrolment schemes was people living outside the school's enrolment home zone might be fooled into thinking they were not going to be able to enrol their boys at the school.
However, he did not believe that would be the case for those living outside King's new home zone.
He said many "zoned'' secondary schools in Dunedin used a ballot system to choose which out-of-zone pupils to enrol.
"The only reason you have a ballot system is when you have more applications than there are places available.
"We're expecting that we'll have somewhere in the vicinity of 220 places available at year 9 in 2017.
"Our expectation is that will be in line with the number of applications.
"And therefore, regardless of where people live in Dunedin, we think they are almost certain of getting in.''
