Later today, Blue Star is expected to announce that it has bought a majority of Wang Laboratories' shareholding in Wang New Zealand and that it is seeking to buy all other outstanding shares in Wang that it does not already own.
Blue Star and Wang Laboratories currently both hold around 30% each of Wang New Zealand.
Earlier this month, Blue Star group founder Eric Watson became the largest individual shareholder in US Office Products, following an agreement by USOP to purchase the remaining 49% of Blue Star that it did not already own.
Blue Star, which has made many acquisitions in the past two years, has doubled in size since USOP bought 51% of the company earlier this year.
Blue Star has acquired 28 companies in New Zealand. The group employs more than 1600 staff and is the country's largest provider of office technology, office products and services.
