Fonterra said it had asked the NZX for its shares and units to go on a trading halt this morning pending an announcement tomorrow about its capital structure.
The exchange has approved its request.
The trading halt would provide Fonterra shareholders and unit holders a full day to review and consider the materials before trading recommences.
"Following tomorrow's announcement, the trading halt will remain in effect until the market opens on Friday 7 May, to provide Fonterra shareholders and unit holders a full day to review and consider the materials before trading recommences," Fonterra said.
