An Australian man will have to leave his family and find his own way home after being kicked off a cruise ship following an altercation onboard.

The 44-year-old man assaulted another male passenger on the ship following an altercation about 9.30pm yesterday, Snr Sgt Anthony Bond said.

Police were advised and attended when the ship docked at Port Chalmers this morning.

After speaking to all parties, and taking into account the circumstances, police warned the man for the assault, Snr Sgt Bond said.

He was also excluded from the ship, meaning he would have to leave his family he was travelling, as well as make his own arrangements to get back to Australia.

The other man received medical attention onboard for a cut to his nose, Snr Sgt Bond said.
