Downer contractors Tim Dhinakar and Mike Fraser put the first speed-limit sign up at Hogans Gully Rd to indicate an 8km zone on the gravel road and a 70km limit on Lake Hayes Rd.
The rest of the signs will go up on March 1 and will affect roads such as the Lake Hayes-Arrowtown Flat Rd, Cardrona Valley Rd and Slopehill Rd. Four signs will go up on Kelvin Heights Peninsula Rd.
The councils are asking that motorists pay close attention to signage when new speed limits come into force around the district this Friday.
The changes were adopted by the council in December last year and most involve reductions in the existing speed limits.
Queenstown Lakes District Council transport manager Denis Mander said people would need to be alert.
''Signage will be going up over the next week so it should be quite obvious to people who use those roads regularly where a change will be taking place.
''All motorists should be checking signs and making sure they're driving to the correct limit.''
The roads affected from Friday are:
• Esplanade Reserve, Hawea
• Aubrey Rd and Outlet Rd, Wanaka
• Old Racecourse Rd and Ewing Pl, Albert Town
• Cardrona Valley Rd, Wanaka
• Orchard Rd, Wanaka
• Studholme Rd (South), Wanaka
