Western Star is one of the oldest Australian butter brands, made in Victoria since 1926 and a fixture of Australian supermarket dairy cabinets. It came to Fonterra through its Australian business and passed to Lactalis with the 2026 sale of the consumer division.
Fonterra sold its entire global consumer business to Lactalis, agreeing the sale in August 2025 for NZ$3.845 billion and completing it on 31 March 2026; resolving a separate dispute with Bega Cheese took total proceeds to NZ$4.22 billion. It moved a century of New Zealand household dairy brands, Anchor and Mainland among them, to a French family company in a single transaction, and turned Fonterra into a business-to-business supplier that now sells milk and ingredients to the buyer of its own brands under agreements running at least ten years. Fonterra kept the Anchor consumer brand in Greater China.
