National's byelection promise was criticised as pork barrelling after its candidate Mark Osborne made the announcement alongside Simon Bridges. The promise was to upgrade 10 bridges within six years - giving National until 2021 to fulfill it. At the time, National promised it would deliver on the promise even if it lost the byelection and Prime Minister John Key has said National hopes to regain the seat in 2017.
The estimated costs National provided for all ten were between $32 million and $69 million. NZTA estimates for roading realignment and bridge upgrades for the four it has approved total $44 million.
The NZTA has included funding for safety improvements for State Highway One and designate a major trucking route along Mangakahia Rd as state highway, meaning that NZTA rather than local councils cover the $5 million cost of maintaining it.
Mr Bridges said National remained committed to delivering on its promise of 10 bridges, even if it had to dip into a different Crown pocket rather than rely on the Transport Agency for funding.
He said the preference was for them to be funded by the NZTA but the Government could use Crown funding and would do so even for those bridges that the NZTA did not believe needed upgrading. He denied that effectively meant taxpayers would foot the cost for upgrades that were not needed for the sake of a political argument. He said the Government believed the upgrades were important to local communities for safety and tourism reasons.
He said National had always said it would be over six years and the most urgent upgrades - in Matakohe, Kaeo and Taipa - would be done over the next three years. "We've made it quite clear we are committed to doing those, we will do them over six years."
