The Australia & New Zealand Infrastructure Pipeline (ANZIP) portal, developed and hosted by Infrastructure Partnerships Australia, lists 25 New Zealand-based projects and 90 Australian-based projects being run by government agencies, local authorities, state-owned enterprises and publicly-listed companies.
New Zealand finance minister Bill English said: "The launch of ANZIP signals a joint commitment to building a more integrated infrastructure market between the two countries."
The "comprehensive view of the Australian and New Zealand infrastructure markets offered by ANZIP will increase certainty around the forward work program for investors, constructors and governments alike", the governments said in a joint statement.
"Both nations have ambitious infrastructure building programs," said Australian treasurer Scott Morrison.
"As part of our national economic plan, the Australian Government is investing a record $50 billion (£31 billion) in infrastructure to support economic growth. There are over 1,000 projects currently underway across Australia, including roads, airports, bridges and passenger and freight rail," Morrison said.
