High seas along Clifton shoreline last week undermined six to eight metres of land by the Marine Club and motor camp.
The Marine Club cannot use one of its two boat ramps now and the Clifton Beach Reserve Motor Camp had to move some caravans and cabins.
Club president and Clifton Domain Board member Steve King said the community had not lost anything they were not expecting to lose because they knew what was vulnerable. Erosion had taken more of the old road to Clifton but the club was optimistic the new road would last a long time.
The road had not been damaged in the swells, although land near the road had been swept away.
"When we first moved the road the sea recovered quite a bit of land but we're optimistic it might stay a long while yet," Mr King said.
Caravans at the motor camp had been moved away from the shoreline and cranes had to relocate cabins that had been undermined by the high seas.
Erosion in the area has been an issue for years and damage to an old sea wall meant there was little protection against the waves.
The Marine Club had met the Hawke's Bay Regional Council but had not been given permission to rebuild the wall because resource consent was required to ensure it was properly constructed.
The Hawke's Bay Regional Council had not received a consent application.
Aside from getting resource consent, which would be difficult, the club could not afford to repair or rebuild the wall even if permission was given, Mr King said. It was hard to know whether a repaired wall would have helped prevent the erosion.
Haumoana resident and spokesman for the Cape Coast erosion lobbying group, Walking on Water, Keith Newman said the sea had rapidly eaten into the land and threatened to undermine sections of the latest access road.
The remains of previous protection, placed to protect the road over many decades, was removed earlier this year leaving the area vulnerable, he said.
