Far North Holdings plans to resurface and widen the concrete ramp which offers all-tide access to Kerikeri Inlet.
The $26,000 improvement will be welcomed by boaties using the one-in-seven-gradient ramp, but the work will limit use of the ramp next week.
The ramp will close on December 13 to 14.
Far North Holdings general manager Chris Galbraith says the work had been scheduled so that tides would be at their lowest when the new ramp surface is poured.
"We are using an exceptionally fast-curing and hard concrete, so a little rain won't be a major problem.
"Should there be a significant rain event, we will postpone the work until March/April next year," Mr Galbraith says.
Boaties seeking all-tide access to Kerikeri Inlet on these days are asked to launch their boats at Rangitane, Opito Bay or Doves Bay instead.
Mr Galbraith apologises for any inconvenience the closure causes, but is confident boaties will be pleased with the improved ramp.
Deck repairs on nearby Waipapa Landing Bridge begin next week as well.
