About 70-100 people stayed at a marae overnight and Bayley said they would be removed today, weather permitting.
Bayley said it would be a couple of days work to get the inland road to Kaikoura open to one lane.
The coastal road was a more challenging prospect.
He said power and telecommunications in Kaikoura had been "intermittent".
Bayley warned people to be prepared for aftershocks.
If it was safe to stay at home, then continue to do so, but do not run outside, he said.
He repeated advice to "stop, drop and hold" to make yourself a smaller target, and not to stand in a doorway.
In Wellington, public transport is now running, including trains on the main trunk line, but services from Wairarapa are restricted.
