Seismologists are keeping a close eye on a "swarm" of quakes that have been recorded around the South Island's Alpine Fault.
But there's no immediate cause for alarm of a big shake along the fault, which poses one of New Zealand's biggest geological hazards.
More than a dozen quakes have been recorded around the boundary - running along the spine of the South Island - since yesterday, including four quakes that measured 4.4, 4.7, 3.8 and 3.1.
