Yes, they are both located on the Pacific plate boundary, which is moving to the northwest.

Christchurch, New Zealand has experienced several significant earthquakes, with the most notable being the Canterbury Earthquake sequence in 2010 and 2011. These earthquakes caused widespread damage and loss of life in the region.
definitely yes they had a 7.1 on the magnitude scale
Christchurch, New Zealand has experienced significant earthquakes in the past, particularly the devastating earthquake in 2011. However, seismic activity has decreased since then, and the city is not currently as prone to frequent earthquakes as it was in the aftermath of the 2011 event.

There are about 5606.314 miles between Okinawa, Japan and Christchurch, NZ.
about 275 that are felt by humans
The first one was at least 7.4 but got down graded to 7.1. For information on earthquakes, please see the related link below.
Christchurch, New Zealand, can experience small earthquakes on a daily basis due to its location near the boundary of the Pacific and Australian tectonic plates. However, the frequency and size of these earthquakes can vary, and it is not accurate to say that the city experiences exactly 2 mini earthquakes every day.
The Movement of Techtonic Plates causes the earthquakes in Japan.
The most recent one was in Christchurch, New Zealand.
The 2010 Christchurch earthquake was of magnitude 7.1. The 2011 Christchurch earthquake was of magnitude 6.3. The 2011 Japan earthquake was of magnitude 9.0. The formula for comparing the energy released by two earthquakes using the moment magnitude scale (which is what I assume those numbers are in, since it's the most common scale for large earthquakes) is D=103*(m1 - m2)/2 So compared to the more recent Christchurch earthquake, we get that the Japan earthquake was about 103*(9.0-6.3)/2 = 103*2.7/2 = 104.05 which we can tell even without actually doing the calculations is a bit over 10,000 times more powerful in terms of total energy released. (this does not, however, mean 10,000 times more damage).
