Stockdale referred to the delay of proposed projects such as the Katikati bypass, Ōmokoroa interchange and Tauranga Northern Link.
"The concern AA has is that we are not necessarily going to see any improvements as a result (of the increase)."
Stockdale acknowledged there were safety upgrades under way on State Highway 2 between Waihī and Tauranga but said "it won't help deal with the congestion, or fuel consumption from people stuck in congestion, not as much as a bypass [around Katikati] would".
Stockdale said each person's total dedicated fuel tax contribution into the National Land Transport Fund was about $870 a year and did not include other taxes such as GST.
"We are paying more than ever in tax."
Minister Twyford said the excise tax would cost a person about $40 a year extra and would go "towards transport improvements that will benefit them and their communities for decades to come".
Twyford said, in a written statement, the Government was spending $801m in transport investment over the three years. This included $101m of safety improvements on SH2 between Waihī and Ōmokoroa.
Other projects in the region funded through fuel taxes include the $120m upgrade to the Baypark to Bayfair link.
