The organisation representing New Zealand dairy companies hopes Japan's bid to be part of the Trans-Pacific Partnership negotiations will not delay the conclusion of talks beyond October.
Talks on a proposed TPP free trade pact involve 11 countries including New Zealand, Australia and the United States. Japan has indicated it wants to be the 12th country.
The Dairy Companies Association of New Zealandrepresents most milk processors, including Fonterra, Tatua and Goodman-Fielder.
Chairman Malcolm Bailey said the timeframe for the conclusion of TPP negotiations will put pressure on Japan as it will have to go with what has already been agreed to by the other countries.
He warns Japan's agricultural lobby will be wary of proposals in the agreement, though overall Japan sees the free trade deal as beneficial to its economy.
