Mr Gliddon said the series of curves would be straightened which would benefit users of this road by improving safety, reducing travel times and will make the movement of freight to the Port of Tauranga more efficient.
Mr Gliddon said a passing lane would also be installed to enable motorists travelling towards Rotorua from Paengaroa to overtake safely.
A gully will be filled from material taken from the Pareteiro hillside which will help to form the new sweeping curves replacing the existing series of tight sharp curves.
Mr Gliddon said the work formed part of the NZTA's Safer Journeys strategy which adopted the world-leading Safe System approach in achieving safer roads and roadsides, safer speeds, safer vehicles and safer behaviours.
For the first several months works will be off the highway and drivers should expect only minor interruptions at times for machinery or deliveries to access the construction site.
As the project progressed, Mr Gliddon said there would be some interruption to travellers along SH33. The project is expected to be completed by March 2014.
"Drivers will be informed of the expected interruptions before they occur.''
In the meantime, Mr Gliddon said drivers needed to be cautious of machinery going to and from the construction site.
The project is estimated to cost $3.6 million and is being managed by Rotorua District Council as the NZTA's project partner for the Rotorua area.
