The Government has confirmed access for New Zealand businesses to more than $US1 trillion in overseas government contracts.
New Zealand has signed up to the World Trade Organisation's Agreement on Government Procurement, which will come into effect next month.
Economic Development Minister, Steven Joyce, said New Zealand businesses will have guaranteed access to bid for annual government contracts in 43 counties, including the United States, Canada and Japan.
Overseas companies already have access to New Zealand procurement contracts.
The agreement covers the purchase of a broad range of goods and services that government agencies buy from the private sector, including construction.
