Rector Dan Reddiex said May 6 was the deadline for feedback on the proposed "home zone''.
We will take that feedback on board and then either make alterations, or forge forward with the proposed enrolment scheme and seek to get that approved by the Secretary for Education.''It was hoped the zone would be approved to take effect later in May.
Mr Reddiex said the proposed enrolment zone was not expected to have any impact on the school's year 9 enrolments for next year.
"The danger with enrolment schemes is that people think they are outside the enrolment home zone and therefore they are not going to be able to get in.
"We don't believe that's going to be the case.''
Many "zoned'' secondary schools in Dunedin used a ballot system to choose which out-of-zone pupils to enrol, he said.
"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.''
King'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.
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 roll exceeded the cap this year, it would be brought forward to apply from May 1 this year.
At the time, ministry enablement and support head Katrina Casey said it would ensure the network of schools across Dunedin was used well, in the interests of all pupils, because there were plenty of spare spaces at other schools that educate boys.
Unfortunately, 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.
"I expected our roll would be really close to 1035 pupils this year.
"We ended up with 234 year 9 pupils, which was about 10 more than I had anticipated and, therefore, we were just slightly over,'' Mr Reddiex said.
The roll was not expected to grow any further, he said.
"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.''
