Repairs to a major underslip on Galatea Rd will now require the closure of the road until May 18 and will involve delays for motorists.
Originally the Whakatane District Council website stated the part of Galatea Rd where the slip is, 3.6km north of the Matahina Dam, would be closed until April 24.
Work began on the site this week and were anticipated to be completed towards the end of June, with progress dependent on the weather and ground conditions.
Council transportation manager Martin Taylor said the affected section of road was badly undercut during the major weather event that hit the district in April last year, which reduced access to one lane.
