The upgrades at both sites will be in place for the start of the 2014 packing season.
EastPack regional operations manager Kerry McCree said the new software would provide greater throughput of both green and gold kiwifruit, and result in overall efficiency gains.
"The optical grading system will segregate incoming fruit into various quality sets.
"Obvious Class 1 kiwifruit will be directly fed to the packing line by existing unstaffed packing tables, and non-Class 1 fruit will be removed without the need for human intervention," he said.
Katikati kiwifruit grower Neil Magnus said EastPack's investment was an indication of the company's support of growth in the Katikati area.
Mr Hawken said EastPack's strong financial situation and its successful Growing Excellence programme enabled it to make ongoing capital investment.
