Overview

ACG Schools, formerly known as ACG Education, is a New Zealand-based private education group that operates schools and preschools in New Zealand and Asia. The group developed from the establishment of Senior College of New Zealand, founded by Sir John Graham and Dawn Jones in the mid-1990s as a school serving senior students. ACG was incorporated as a New Zealand limited liability company in 1994 and established its first school during the same period. The organization subsequently expanded from its original school platform into a broader education network comprising independent schools, early-childhood provision, English-language education, and vocational colleges. The group's New Zealand independent-school network has included ACG Parnell College, ACG Strathallan, ACG Sunderland, and ACG Tauranga. These schools are secular and co-educational and have taught toward Cambridge International qualifications. ACG has also operated Zig Zag Zoo, a preschool centre in Queenstown. Outside New Zealand, the group has operated or been associated with international schools including Australian International School Vietnam and ACG School Jakarta. The reference material describes the wider organization as delivering education to more than 4,700 students through 10 campuses in four cities, although the exact current campus count and operating footprint may change over time. ACG's development included expansion beyond conventional school education. In 2017, ACG Education announced the purchase of The Campbell Institute, an English-language school, and later that year acquired seven New Zealand vocational colleges from Intueri Education Group. These transactions broadened ACG's activities into language and tertiary vocational education, although the subsequent ownership and operating status of those businesses should be checked against current corporate records. The group underwent significant ownership changes during the 2010s. Waterman Capital acquired a 24 percent shareholding in ACG in February 2013, and its executive director Matt Riley joined the board. In September 2015, Pacific Equity Partners announced an agreement to acquire ACG for an undisclosed amount after a sale process involving UBS and Macquarie. In 2019, ACG was acquired by Inspired Education Group, also for an undisclosed sum. The acquisition placed ACG within an international private-school group while preserving ACG as a recognizable education brand. ACG's school model is positioned around private, co-educational schooling with an international academic orientation, particularly through the use of Cambridge International Examinations. Its services span primary and secondary education, preschool provision, language instruction, and, during part of its expansion, vocational education. In 2018, ACG Senior College closed and was scheduled to merge with ACG Parnell College. ACG Parnell College subsequently opened a senior campus in 2019 for Year 12 and Year 13 students. Because school portfolios, legal ownership, and campus operations can change, the current structure should be confirmed through Inspired Education Group and individual school sources.

History

ACG Schools emerged from the development of private education in New Zealand during the 1990s. The company was incorporated as a New Zealand limited liability company in 1994 and established its first school around the same time. Its founding educational institution was Senior College of New Zealand, established by Sir John Graham and Dawn Jones in 1995. The school was designed for senior students and became the foundation of the wider ACG group. Over the following years, ACG expanded into a network of independent schools and related education businesses. In New Zealand, its school portfolio came to include ACG Parnell College, ACG Strathallan, ACG Sunderland, and ACG Tauranga. The schools were described as secular and co-educational and used Cambridge International Examinations as part of their academic offering. ACG also operated Zig Zag Zoo, a preschool centre in Queenstown. Its international activities included Australian International School Vietnam and ACG School Jakarta, giving the group an operating presence beyond New Zealand. The organization also pursued diversification. In 2017, ACG Education acquired The Campbell Institute, an English-language school. On 1 July 2017, it acquired seven New Zealand vocational colleges from Intueri Education Group. These deals extended the group into language and vocational education, although the later status of those businesses is not established by the available material. ACG's ownership changed several times. Waterman Capital obtained a 24 percent stake in February 2013, with its executive director Matt Riley joining the board. In 2015, ACG appointed UBS and Macquarie to conduct a sale process. Pacific Equity Partners announced an agreement to acquire the company on 17 September 2015; the consideration was not disclosed. In 2019, Inspired Education Group acquired ACG, again for an undisclosed amount. This transaction made ACG part of a larger international private-school platform. The group's school structure also changed. ACG Senior College closed in 2018 and was set to merge with ACG Parnell College. In 2019, ACG Parnell College opened a senior campus for Years 12 and 13. The available reference material describes ACG as educating more than 4,700 students through 10 campuses in four cities and as New Zealand's largest independent private-schools group at the time of the cited description. Current enrollment, campus count, ownership arrangements, and management are not independently confirmed here and should be treated as subject to change.
