What is a traditional Maori wake like?
One of the features is that the Guest of Honour is present in an open coffin.
It lasts a couple of days, and today, there are a mix of traditional ceremonies, and something approaching a party - often a very boisterous party, where the deceased is remembered.
Not sure how it would work with someone who's being given a state funeral. Traditionally, the wake is held at the family's home & everyone gathers there. Family members take turns staying with the deceased, so the deceased is never left alone. As naturalman said, the Guest of Honour is present in an open coffin. Someone is with them 24/7. It lasts for three days & after the funeral everyone gathers again for food & drink.
