"Those who drive this road can't afford to wait for a change of Government to get the job done ... It is simply not good enough."
Muller said the National Party committed to invest $520m to upgrade the stretch of SH2 to a four-lane expressway to make it safer and more efficient.
Last night a person was killed in the intersection of Pahoia and Esdaile Rds when a car and truck crashed. Read more here.
The crash comes a day after a SH2 action group announced plans to block the road next weekend in protest against Government inaction on safety and capacity concerns.
The meeting organised by Muller will be at 4.30pm, after the community's 3pm march.
Andrew Hollis, one of the campaign's organisers, said time had been chosen for a 30-minute protest hikoi across the Wairoa Bridge as organisers hoped it would be the least disruptive time for locals.
"We want to keep the pressure on the Government, not the pressure on the community. We don't want to upset everyone in Tauranga by blocking roads."
They were working with local police to ensure the protest would be safe, he said.
Matthew Farrell, another organiser, said the goal of protesting was to put pressure on the Government and Transport Minister Phil Twyford to instruct the NZ Transport Agency to prioritise and speed up its decision-making process regarding the future of multiple roading projects planned for the area, including the Tauranga Northern Link.
Asked on Sunday if he would intervene to speed things up, Minister Phil Twyford said: "The experts need to be able to do their re-evaluation free from political interference."
He also said the Government was investing $87 million in safety improvements to save lives on the road.
"That will deliver quick results, which a four-lane expressway that would take years to build would not," Twyford said.
