Letbe a positive integer andthe finite field withqelements. In this paper, we consider ther-regular complete permutation property of maps with the formwhereis a PP over an extension fieldandis an invertible linear map over. Whenis additive, we give a general construction ofr-regular CPPs for any positive integerr. Whenis not additive, we give many examples of regular CPPs over the extension fields forand for arbitrary odd positive integerr. These examples are the generalization of the first class ofr-regular CPPs constructed by Xu et al. (Des Codes Cryptogr 90:545–575, 2022).
