"For insurance, we partnered with Manawatu, Whanganui, Bay of Plenty and some South Island councils to achieve more than $3million worth of savings for the 25 councils involved."
Wairoa District Council chief executive Fergus Power said he supported the economy of scale achieved by HB LASS.
"Through our efforts, Hawke's Bay saved $930,000 for the 2015/16 year insurance programme, while the GIS shared service also saved $170,000 in joint software purchasing."
His regional council counterpart, Liz Lambert, is also a project advocate.
"We're confident we can deliver more savings through joint procurement and by aligning contracting programmes for shared services across the region," she said. "This is good for our region and our ratepayers."
HB LASS said in a release it was established to investigate, develop and deliver shared services, where and when that could be done more effectively for any combination of some or all of the shareholding councils.
Insurance, information services, GIS and fuel are currently shared services.
The company is owned by the Central Hawke's Bay District Council, the Hastings District Council, the Napier City Council, The Wairoa District Council and the Hawke's Bay Regional Council.
Each council CEO is a director of the company.
According to the regional council the driver behind it has so far been to improve service levels, lower costs, improve efficiency and increase value through innovation for Hawke's Bay ratepayers.
