	Injection into the MAX IV storage rings will not make use of a conventional local injection bump with four dipole kickers. Instead, pulsed multipole injection will be applied. Previously, it was foreseen to use a pulsed sextupole magnet similar to what KEK had originally designed for the PF ring. But after seeing encouraging results with a prototype nonlinear kicker magnet developed for BESSY II, pulsed multipole injection for the MAX IV storage rings was revisited. A nonlinear kicker magnet similar to the BESSY-type can be realized for both MAX IV storage rings. Such a nonlinear kicker offers a broad zero-field region around the center which does not perturb the stored beam, while offering a high-field region around the location of the injected beam making it ideal for top-up injection. This paper summarizes the proposed kicker magnet design and shows beam dynamics results from multi-particle tracking studies. A comparison with the previous PSM design is also included.
