  The near horizon geometry of general black holes in equilibrium can be
conveniently characterized in the formalism of weakly isolated horizons in the
form of the Bondi-like expansions (Krishnan B, Class.\ Quantum Grav.\ 29,
205006, 2012). While the intrinsic geometry of the Kerr-Newman black hole has
been extensively investigated in the weakly isolated horizon framework, the
off-horizon description in the Bondi-like system employed by Krishnan has not
been studied. We extend Krishnan's work by explicit, non-perturbative
construction of the Bondi-like tetrad in the full Kerr-Newman spacetime.
Namely, we construct the Bondi-like tetrad which is parallelly propagated along
a nontwisting null geodesic congruence transversal to the horizon and provide
all Newman-Penrose scalars associated with this tetrad. This work completes the
description of the Kerr-Newman spacetime in the formalism of weakly isolated
horizons and is a starting point for the investigation of deformed black holes.
