CHRISTCHURCH, New Zealand, Sept. 8 (UPI) -- Aftershocks knocked out power in Christchurch, New Zealand, Wednesday, delaying repairs to the city's earthquake-damaged waterlines, officials said.
Officials said the rumblings reversed some of the work done Tuesday, and more parts of the city were without water, Radio New Zealand reported.
The 5.1-magnitude and 4.1-magnitude aftershocks followed last week's 7.1-magnitude earthquake.
The Civil Defense agency warned more aftershocks could occur, and an aftershock as strong as a magnitude-6 could be expected.
Civil Defense Minister John Carter told Parliament Wednesday the recovery would take months instead of weeks, Radio New Zealand said.
Carter also said demands for assistance would rise and more welfare centers likely would be needed.
