According to Fix the Bloody Road campaign spokesman Matthew Farrell, it was the unknowns and the months of continuing delays for answers that had the community boiling over into protest action.
"Of course anyone in their right mind welcomed the safety improvements, but we still have three out of four projects on ice, and every six months the decision moves out another six months."
Farrell said the funding and work the agency had committed to was "far short" of what was needed.
It was "not realistic" for the Government to try and get rural people out of their cars, he said: highways were a necessity.
"The urgency is because we are already well behind the eight-ball, and hundreds of new homes are being built. They need to pull finger and commit some funding."
The NZ Transport Agency has said three projects supported by the previous Government were being entirely re-evaluated, including the Katikati bypass and Tauranga Northern Link.
This could take up to four months.
