"[It] will help transform the cathedral into a tourism attraction that will showcase the sometimes turbulent story of European settlement in Taranaki and the relationship between Maori and Pakeha over 175 years," Mr Jones said.
The work is expected to start in mid 2019 and take about 15 months.
The biggest amount on the list is the $13.3m going to supporting upgrades and the expansion of hiking trails around Mount Taranaki and the National Park.
"The first phase of today's commitment will be a comprehensive investigation of the best ways to promote tourism in the Taranaki region and enhance biodiversity on Taranaki Mounga, and how the proposed crossing tracks fit into that," Jones said.
The region's Forgotten World Highway — SH43 — is also getting a look-in. $400,000 has been allocated to investigating its tourism value ahead of a possible revamp.
The investment into SH43 will occur before a possible multi-million dollar upgrade to the road.
The route, from Stratford to Taumarunui, is a freight route and increasingly popular with tourists, but a 12km stretch through the Tangarakau Gorge remains unsealed.
"SH43 takes you through some wild and beautiful parts of Taranaki, but it's not an easy drive," Jones said.
"This preliminary work will identify the likely economic benefits of an improved SH43, and the costs, and assess how upgrading it can ensure SH43 preserves its character as one of New Zealand's most unique state highways," Shane Jones said.
While earlier studies have investigated sealing the final 12km, this work will also look into improving resilience and safety on SH43, as well as improving signage, road markings and looking at speed management along the route.
Friday's announcement also includes a raft of other feasibility studies. About $500,000 is set aside for reviews.
The funding feeds into a broader plan launched yesterday aimed at diversifying Taranaki's economy beyond its fuel and agricultural sectors. The region itself is expected to chip in another $16m.
