We obtain a new class of stationary axisymmetric spacetimes by using theG\"urses-G\"ursey metric with an appropriate mass function in order to generatea rotating core of matter that may be smoothly matched to the exterior Kerrmetric. The same stationary spacetimes may be obtained by applying a slightlymodified version of the Newman-Janis algorithm to a nonrotating sphericallysymmetric seed metric. The starting spherically symmetric configurationrepresents a nonisotropic de-Sitter type fluid whose radial pressure $p_r$satisfies an state equation of the form $p_r=-\rho$, where the energy density$\rho$ is chosen to be the Tolman type-VII energy density [R. C. Tolman, Phys.Rev. {\bf 55}, 364 (1939)]. The resulting rotating metric is then smoothlymatched to the exterior Kerr metric, and the main properties of the obtainedgeometries are investigated. All the solutions considered in the present studyare regular in the sense they are free of curvature singularities. Depending onthe relative values of the total mass $m$ and rotation parameter $a$, theresulting stationary spacetimes represent different kinds of rotating compactobjects such as regular black holes, extremal regular black holes, and regularstarlike configurations.
