Overall, the policy appears to borrow significantly from New Zealand First's regional development policy proposals.
The detail in the policy is really limited to comments about rail lines in Gisborne, including a proposal to connect Gisborne to Kawerau with a new rail line. This is likely to be a rehash of the ancient Gisborne-Opotiki proposals (which became in part the Moutohora Branch, closed in 1959).
The Moutohora Branch proposal was canned in 1959 by Labour. It had been under serious consideration for decades at that time. The government of that period essentially sent the signal that it would not ever be a priority for completion. Although from time to time the proposal is refloated, it isn't very likely to ever happen.
