A piece of Arrowtown land was purchased by the wife and son of a Singaporean chocolate mogul.

The sale of sensitive land near Queenstown went ahead after the buyers agreed to donate $100,000 to the local high school to fund iPads and laptops.

David Chuang and Lim Mee Len were approved by the Overseas Investment Office (OIO) to purchase the $2.7 million for a 19-hectare piece of Arrowtown land, under the name Glenorchy Homestead Limited, in January.

The pair are the wife and son of Singapore rich-lister John Chuang, who made his millions in the chocolate confectionery business.

It was previously reported the applicants planned to use the property as a home.

The condition for approval was the buyers donate $100,000 to the Wakatipu High School Foundation.

The decile-10 secondary school has a 'bring your own device' policy as a requirement for all 850 students.

The school's principal Steve Hall wrote to the OIO saying 5 per cent of all students would need their full cost of devices to be covered, and 25 per cent would need to be partially covered, with the rest not needing assistance.

About $70,000 of the sum would go toward assisting parents to buy devices, and $30,000 would go toward training teachers, he wrote.

"In addition to the funding assistance required for families for devices, professional learning for staff will need to continue in order to prepare staff to provide the best possible learning experiences for students."

Labour's education spokesman Chris Hipkins said the Government must address the inequality laptops and tablets in classrooms.

“If parents at a decile 10 school can’t afford digital devices for their kids, how can those at other schools be expected to?" he said.

"School kids shouldn’t have to rely on overseas investors to ensure they get their fair shot at education. The law guarantees every Kiwi kid a free schooling, and that’s what the Government has a responsibility to fund.”

The Minister of Education, Minister for Land Information and the Overseas Investments Office have been contacted for comment.

The Government does provide for internet funding, investing more than $200 million in the 'N4L Managed Network' so all state, state-integrated and partnership schools can have secure and uncapped internet.
