An appeal to the port's expansion has delayed work but mediation between the parties involved is now under way.
But Jones was far from impressed with Ngāti Oneone's opposition.
"I think what I'll do when I go to Gisborne, I will ask the brain researchers to meet with the hapū – they obviously need help."
Jones was referring to the Gisborne's new Matai Medical Research centre, which was provided $6 million through the Provincial Growth Fund (PGF) this morning.
It focuses on "traumatic brain injuries".
Jones said the Ngāti Oneone's opposition to the Port's expansion was standing in the way of greater employment opportunities in the region and that the Resource Management Act (RMA) has become a "plaything for hapū mischief-makers".
"Hapū activists cannot be allowed to get a free pass in this type of concern.
"We're never going to develop in a broad sense these regions if we don't improve our infrastructure."
This is not the first time Jones has taken aim at Māori opposition to project developments in the Hawke's Bay area.
Last month he criticised Ngāi Tūhoe for opposing the sealing of a 10km road on State Highway 38 – the project had been given $10 million from the PGF.
Jones said that Tūhoe needed to accept that, post-Treaty settlement, it can no longer throw its weight around and alienate its neighbours.
"That is why the road needs to continue. This type of hillbilly thinking is totally irrelevant to my political mission and I am not indulging it one inch."
A spokesman for Ngāti Oneone has been approached for comment.
