The current study presents a direct comparison of the level of association of ingroup favoritism and outgroup hostility with opposition to multiculturalism policies in New Zealand. With both predictors operationalized as affect ratings of warmth and anger across separate models, ingroup favoritism and outgroup hostility were independently associated with European New Zealanders’ (N = 10,869) opposition to both resource-specific and symbolic policies. Furthermore, ingroup favoritism was more strongly associated with opposition to resource-specific policies which represent high realistic threat (compared with symbolic policies). In contrast, outgroup hostility was more consistently associated with both policy domains.
