Emergency services responded to today's crash about 5.45am.
The four-wheel-drive Land Cruiser vehicle was on its roof on the side of the road when the first fire crew arrived.
Te Araroa and Tikitiki firefighters responded, along with police. St John ambulance from Ruatoria was also called out.
St John officers pronounced the victims dead at the scene.
Pahuru-Huriwai confirmed the victims were from the same whānau as the crash on October 15.
Te Araroa fire chief Dick Cook attended both crashes and knew the whānau personally.
It was "too soon" to provide any further details and he did not want to say anything about the whānau before police released their names.
"We are in a small rural area, everybody knows everybody. It's really tough, but the hardest part is having to just turn around and go off to your real job."
Pahuru-Huriwai said it had been a tough period for the small community.
"I've been in touch with the wider whānau today, and all are devastated. It is incomprehensible what has happened.
"The family will be sorely missed in our community. We have had a lot of death this year.
"And any death is a tragedy but when it involves our children, close members of a family, it is very hard to find the words to express the pain our community is feeling.
"I don't think in my lifetime we will have had a tangi like this, three on the marae."
Pahuru-Huriwai said they were also concerned for the welfare of their first responders.
"By the very nature of their jobs they are all connected to the people involved in this accident and the previous one.
"I'd like to say for everybody to just take care of each other, and be careful on the road.
"This is not the kind of accident that happens every day, and to have this happen so soon after the last one is quite unimaginable."
The road was closed this morning but reopened this afternoon.
The police Serious Crash Unit from Gisborne is investigating.
A police spokeswoman said there was no update, and they were not yet ready to release names of the victims.
Gisborne mayor Rehette Stoltz said there's a sombre mood across the East Coast community following this morning's tragedy.
"They had a death a while ago and then this today, so everyone is hurting and are sending support to the family involved".
She said she was aware of the people involved but wouldn't confirm who they were and whether the two crashes were connected until it was officially confirmed.
New Zealand's road toll so far this year to November 15 is 274, down from 294 at the same time last year.
However, eight people had died by Sunday in the Gisborne district so far this year, up from just three at this time last year. Today's three deaths will lift this year's tally to 11.
