Pauline Hanson has urged her supporters to buy "non-halal" Easter eggs and avoid brands that offer halal-certified products, such as Cadbury.
But Cadbury Australia's owner, Mondelez International, says it's proud to make products for customers who want halal-certified chocolate.
"We're very proud to make chocolate to suit a diverse range of chocolate fans, and halal certification helps us do that," a spokesperson told AAP.
The One Nation senator made the appeal in a video posted to her Facebook page on Tuesday morning.
It aligns with the party's stance that buying halal-certified products equates to "financially supporting the Islamisation of Australia".

"We see these products out there that are actually halal-certified - Cadbury chocolate for instance, halal-certified," she says in the video.
"Go and buy some non-halal Easter eggs and chocolate and have a happy Easter."
Cadbury Australia lists products such as Mini Eggs, as well as other seasonal and novelty items, as certified halal.
It said the Easter products were also halal-certified because they were made using the same process as core range items.
