2200. There have been 4,422 aftershocks since the 16th January 2013.
The reason that there have been so many aftershocks after the 2010 Christchurch earthquake is because bigger earthquakes have not only stronger aftershocks, but more of them. Aftershocks happen because when an earthquake occurs, the earth's plates hardly ever settle into a stable position straight away. So, the newly moved rock has to be settle.
The duration of the initial earthquake was 30 - 40 seconds. There were several smaller aftershocks.

Yes. There are nearly always aftershocks after a big earthquake. Please see the related question for more information.
No not quite aftershocks can even occur for a couple of days after the main earthquake.

Between 4:35am on Saturday September 4, 2010 and 2:00pm on Sunday 18 September, 2010, there have been nearly 700 aftershocks, with more expected. Aftershocks may continue for weeks. update: A month afterwards and we have had over 2000 aftershocks in Canterbury now. Though the frequency is now decreasing they are still happening with some a few rarer ones still being 4.6 - 5 on Richter scale.
Aftershocks are the results of the Pressure Plates being unstable, and are still adjusting or moving. The earthquake from September 4, 2010 in Christchurch will be having aftershocks for about 1 and a half more years.
