In 2008 an extension was proposed , with a second loop incorporating the Oxford Terrace " strip " and the City Mall on Cashel Street . This was under construction at the time of the 2010 Canterbury earthquake and subsequent February 2011 Christchurch earthquake , as a result of which work was delayed . Part of the second loop , along Oxford Terrace , Cashel Mall and part of Main Street was officially opened on 12 February 2015
