Sarah Holbrok said she had also frequently come across the "bottleneck," and often cars were backed up as people tried to merge.
She thought there would always be a delay at night on the highway because of the ongoing development at Papamoa and the amount of road users.
Mount Maunganui/Papamoa ward councillor Leanne Brown said she had noticed a pinch in the road but it would only be short-lived.
"I think by the time all the roads open and all the options are available, it should flow really well. I would be confident NZTA have done all the right modelling and in the short-term there are some pinch points at peak times."
Humans were creatures of habit, she said, and liked to travel the same road at the same time but they should think about trying different routes.
Tauranga Eastern Link senior project manager Wayne Troughton said drivers were still adjusting to the slip road that led into the roundabout for Papamoa and Te Puke-bound traffic.
"That road has a lot of traffic on it so as soon as you get a little bit of slowing down it has a ripple effect.
"People go from a reasonable speed to next to nothing because they are looking at what is happening ... we call it rubber-necking."
However, he expected that to be eliminated once the toll road opened and about 25 per cent of traffic used it.
"It is expected about 6000 vehicles per day will use the TEL toll road on opening and this will increase over time as the Papamoa East and Rangiuru Interchanges are developed.
"Therefore the traffic volumes on the off-ramp will decrease and there will be less reason for congestion.
"I would be very, very surprised if we have traffic backingup," he said.
The slip lane was a typical design for an off-ramp, he said, and a holistic, conservative approach had been taken in its design.
The single-lane off ramp, which would have a speed limit of 70km/h, assisted in reducing speeds prior to the roundabout, Mr Troughton said.
