The purpose of this paper is to investigate extension problems for the category of finite commutative hypergroups. In fact, sufficiently many extensions will be provided by applying the notion of a field of finite commutative hypergroups. Moreover, the duality of such extensions will be studied via fields of finite commutative hypergroups.
