Rotating black holes do not have a point like singularity.
The singularity is ring like, the ring is in the "equatorial" plane perpendicular to the axis of rotation.
The diameter of the ring is a function of the angular momentum of the black hole. The greater the angular momentum the larger the diameter of the ring. Angular momentum is conserved since the black hole cannot shrink to diameters smaller than the ring.

Due to the ring like property an object falling into the black hole along the axis of rotation can pass through the ring.
