Fonterra is looking to spend $100 million in Australia immediately to "de-bottleneck" its plants.
Chief executive Theo Spierings unveiled the growth plans during the co-operative's annual meeting at its Whareroa site in Hawera yesterday.
Fonterra Australia had reached full milk-processing capacity at two billion litres and the expansion would provide a further 500 million litres of capacity. The opportunity to introduce a co-operative model was also being evaluated.
Priorities outlined for 2018 included protecting its market share of New Zealand milk, delivering "double-digit" foodservice diversified growth, revitalising the Anlene brand, delivering China and the Beingmate partnership "at full potential" and growing the Australian milk pool share.
The co-operative has repeated its 2017-18 season forecast farmgate milk price of $6.75, bringing the forecast total available for payout to $7.20-$7.30.
