This quake, magnitute 6.3, hit much closer to the CBD and during a business day, so the casualty count is much higher.  Being a more shallow quake, much closer to town, but also lesser in magnitude, my uneducated view based on media coverage is that the effects are not as widespread, but where they're felt, are very significant.

The 2010 quake was 10 km deep, which is not that deep. It was 40 km away from Christchurch, however. This quake's epicenter is at Lyttelton, which is apparently only 12 km away, and so it isn't too surprising the damage is heaver. (That depends a lot on the property of the bedrock and sediments, and whether there is any seismic wave reflection and focusing going on.)
