A Christchurch wildlife centre has backed Auckland Zoo's decision to drop Cadbury products.
The zoo pulled the confectionery giant's range from its shops and restaurants after Cadbury began adding palm oil to its chocolate.
Critics say rainforests in South-East Asia are cleared to produce palm oil, pushing orangutans out of their natural habitat.
More than 700 people have joined a social networking group urging New Zealanders to also boycott Cadbury products.
Willowbank Wildlife Reserve director Kathy Rangiwananga said the park backed Auckland Zoo's stance and would consider removing Cadbury products from its restaurant kitchen.
The park did not sell chocolate bars, Rangiwananga said.
Cadbury spokesman Daniel Ellis said the company had independent Green Palm certification for the palm oil it used in its products.
