Planned work to replace the concrete boat ramp at the Tarawera landing will now take place next week.
From Monday, contractors will work to remove the old ramp and construct a new one in its place, Rotorua Lakes Council said.
The ramp and jetty will be closed while work takes place, meaning boaties will need to launch at either Boatshed Bay or Stoney Point.
Originally scheduled for late this month, contractor availability and the deterioration of the current ramp meant the work had been brought forward.
The early start date also means the ramp should be fixed in time for the school holidays.
