He was first rushed to Wairoa Hospital earlier this month.
Police say the investigation into what caused the injuries will take a long time, but that the baby's family are distressed by his death.
The investigation remained focused on establishing the events that led to the baby being admitted to hospital on Saturday, April 13, police said yesterday.
With a police investigation under way, we can't speculate on what could have happened, but the community can mourn a life cut short.
Raynar-Lee did not even have the opportunity to learn to walk before his tragic death.
Whatever the circumstances of this tragedy, he did not deserve this.
We need to do whatever we can to prevent tragedies such as this.
Hopefully the police can establish exactly what caused the death of the baby, so that the authorities - whichever those may be - can address the situation.
For the sake of Raynar-Lee's memory.
