(Adds no reports of injury)
WASHINGTON, Sept 1 (Reuters) - A powerful earthquake of magnitude 7.1 struck off the coast of New Zealand early on Friday, the U.S. Geological Survey said, but there were no immediate reports of injury or damage.
The quake hit 105 miles (169 km) northeast of Gisborne, New Zealand and had a depth of 19.1 miles (30 km), the USGS said.
Twitter users in New Zealand's North Island reported being woken up by shaking. The quake did not pose any danger of a tsunami on the Pacific coast of Canada or the United States, the U.S. National Tsunami Warning Center said.
The Chilean Navy also said it did not expect a tsunami on the coast of the South American nation.
The USGS originally reported the quake as a 7.2 magnitude but later downgraded it to 7.1.
