Sustainability was also celebrated with a new category - Sustainability Project of the Year - taken out by Auckland Transport's City Rail Link team.
ASB Bank also had a successful night, winning Procurement Team of the Year and with general manager for Group Procurement Mark Jones being named Procurement Professional of the Year.
Comvita was awarded the Successful Procurement Change award.
Advisory Partner at EY Scott Blackwood said the awards recognised the significant value that good procurement practices could deliver toward growing New Zealand's economy.
"Every year New Zealand's Government and Private sectors spend billions of dollars on external goods, services and works," Blackwood said.
"A well-established and effective procurement function ensures this money is utilised wisely and delivers real benefits in the form of better economic, environmental, social and Mana Whenua outcomes for our respective organisations and our country."
