It recommended a temporary halt to negotiations so all of Whakatohea could be given a chance to vote on how to proceed and that the Crown commit to maintaining its current settlement offer and pay interest on the cash component of the settlement offer.
Finlayson, the National Party spokesman for Crown-Maori Relations, said suggestions political consideration overrode the need for a just and durable settlement was "wrong and insulting to the Crown and to me personally".
"The agreement in principle negotiated with Whakatohea is one of the largest ever recognising the severe losses suffered by the iwi over many years.
"Throughout my time I worked with Whakatohea over at least seven years to lay the foundations for a successful settlement. Crown officials also laboured for many years with the leadership of Whakatohea to get to a position in 2016 where the iwi was invited to enter into negotiations.
"There was nothing rushed about it. Indeed when I attended the commemorations of the battle of Te Tarata in October 2015 I was criticised by some speakers for taking too long to begin negotiations."
Finlayson said in adopting this approach to the actions of the Crown, the Tribunal had failed to "consider the full history and process of the negotiations".
"The suggestion that the Crown should pay interest is unreasonable. Interest is always paid from the time of the initialling of the deed of settlement and I hope the Crown ignores this recommendation.
"I applaud the statesmanlike approach of Whakatohea leaders who have welcomed the report and the recommendation that there be another ballot – which was always agreed – to resolve these matters.
"I also acknowledge the outstanding efforts of all Crown officials with whom it was my privilege to work on this very important matter.
"The fine leaders of Whakatohea who have worked so hard on these negotiations in recent years deserve to be praised for their efforts and I hope that this report doesn't deter them from seeking a full and final settlement of their grievances."
