Minor damage (VI) in the epicentral area. Felt in northern and central South Island. FAULT PLANE SOLUTION: P-Waves NP1:Strike=173 Dip=83 Slip=-8 NP2:Strike=264 Dip=82 Slip=-173 Principal Axes: (T) Plg=1 Azm=219 (P) Plg=11 Azm=128 Comment: The focal mechanism is moderately well controlled and corresponds to strike-slip faulting with a small normal component. The preferred fault plane is not determined.
