HSBC's New Zealand chief executive Noel McNamara said the programme would see the council lead the way for local authorities to borrow offshore.
"It also clearly highlights the advantages that borrowing in a currency other than New Zealand dollars can provide and ensures the council has the widest range of investors open to it to meet its funding needs," he said.
The council's chief financial officer, Andrew McKenzie, said the successful launch of the facility was part of council's strategy to diversify its funding sources and lengthen the term of its borrowing.
"In going overseas, we will achieve both objectives and leverage off our position as one of the best rated institutions in the country," he said
Auckland Council intends to fully hedge any currency exposure related to the borrowing.
HSBC is part of Hong Kong-based Hongkong and Shanghai Banking Corp.
The move is separate from the newly-established Local Government Funding Agency, which was formed to allow local authorities to club together to sell their bonds offshore.
Auckland Council is one of agency's members, but it can also borrow overseas in its own right because of its size.
