A magnitude 5.4 earthquake has been recorded near Kaikoura, the coastal settlement in the South Island still recovering from a 7.8 quake last year.
The quake was recorded at 5.10pm on Sunday, GeoNet says.
It was centred 10km west of Kaikoura with a depth of 13km.
Of the 1365 people who registered online to say they felt the quake, 793 said it was weak.
Fire and Emergency NZ said it had not received any calls relating to the quake.
Two people died in the 7.8 quake on November 14, 2016. The quake damaged infrastructure around Kaikoura, a settlement famous for whale watching and popular with tourists.
State Highway 1 north of Kaikoura remains closed but is expected to reopen by Christmas.
