"It has to be done between high tides and the preparation of health and safety planning was paramount."
Last week high tides were in the middle of the day, so work could only be carried out in the early mornings and late afternoons.
The walls would help defend the two areas against further sea swells expected over the rest of winter.
In the meantime, Council was in the process of lodging a resource consent application with Hawke's Bay Regional Council to build a 380m sea wall, stretching from in front of the camp to in front of the Clifton Café. It would be for a term of 35 years.
As part of this year's Annual Plan process, Council consulted with the public on whether to proceed with an application to build the wall. The proposal attracted about 3000 public responses, with 72 per cent either in favour of the plan or neutral.
