<p>We study the Cauchy problem of higher dimensional Einstein-Maxwell-Higgs system in the framework of Bondi coordinates. As a first step, the problem is reduced to a single first-order integro-differential equation by defining a generalized ansatz function. Then, we employ a contraction mapping to show that there exists the unique fixed point of the problem. For a given small initial data, we prove the global existence of classical solutions. Finally, by introducing local mass and local charge functions in higher dimensions, we also show the completeness property of the solutions.</p>
