A father and daughter were among many of those standing at the wharf who wanted to pay their respects.
"It's important to remember their families around Christmas time and all those who won't be going home to their families," the father who wished to remain anonymous said.
"It is quietly emotional this morning with everyone standing here trying to show some respect in some way."
It was a somber mood this morning said one woman. She said usually the ships would play Love Boat with the horn, but this morning the ship was quiet and somber.
Cruise passengers can be seen on board their deck, standing and waving back to those at the wharf.
The ship has been docked in Tauranga Harbour for two days and was scheduled to leave the Port of Tauranga at 6.15pm yesterday but this was delayed due to police operational matters.
Yesterday afternoon the booming horn of the ship signalled at 3.59pm, marking the beginning of a moment's silence honouring those ship passengers and crew killed, hurt or still missing from the eruption.
It was a moment not seen before at the Port of Tauranga - local Māori, dignitaries plus passengers and crew from a visiting cruise ship collectively praying for calm and healing.
