"We're constantly managing the price risk and everything associated with that."

However, extra participants on GDT would create a more liquid dairy trading environment and allow for the creation of financial tools which could be used to better manage price volatility, Rivers said.
Another benefit of the partnership was that it would enhance GDT's standing as an independent auction platform.
"I expect that's going to lead to greater volumes being traded on GDT by more participants."
The move was a perfect fit with Fonterra's strategy, Rivers said.
"We expect it's going to support us moving more of our milk into higher-value products while ensuring that there's enough activity on GDT to set a robust Farmgate Milk Price."
As overall GDT volumes grew from a greater number of sellers, Fonterra would have more ability to shift some physical product off the platform, Rivers said.
"We're looking forward to working together with EEX and NZX to grow GDT's presence across Asia and Europe. It's going to support our focus of moving milk into those higher-value products."
