Overnight winds predicted for Canterbury were not as strong as expected.
Power poles and trees in Dunsandel and in Oxford were brought down late on Sunday night - knocking out power for a time.
MetService now says the winds are dying down, with gusts averaging about 50km per hour.
However, heavy rain has fallen in the headwaters of Canterbury's rivers.
There are fears that flooding could hit the region at high tide on Monday morning.
Civil Defence also fears that many stop-banks may not be able to withstand any flooding.
It says the stop-banks may have been weakened by the earthquake.
About 150 people were evacuated from the Riverlands holiday park, south of Kaiapoi, on Sunday because of fears the Waimakariri River could breach its banks.
