  The Jorge-Meeks $n$-noid ($n\ge 2$) is a complete minimal surface of genus
zero with $n$ catenoidal ends in the Euclidean 3-space $\boldsymbol{R}^3$,
which has $(2\pi/n)$-rotation symmetry with respect to its axis. In this paper,
we show that the corresponding maximal surface $f_n$ in Lorentz-Minkowski
3-space $\boldsymbol{R}^3_1$ has an analytic extension $\tilde f_n$ as a
properly embedded zero mean curvature surface. The extension changes type into
a time-like (minimal) surface.
