"We get really good feedback on our coffee. And that's why they come, for coffee and a slice of cake ... because the coffee is poor on the cruise ship," he said.
Despite being busier due to cruise ships, Mr Quinn said the activity wouldn't add enough revenue to warrant hiring more staff.
"Our busiest times would be Christmas and public holiday weekends. A cruise ship would never bring that sort of business to us. But what it does is bring us extra coffees, extra cakes and extra people who tend to sit outside a little longer and just take in the atmosphere," he said.
Mr Quinn said the staff at Ujazi Cafe are made aware of when the cruise ships are coming in through the staff noticeboard that displays the Napier Port's schedule.
"We keep an eye on what times the cruise ships come in and the size of cruise ship. If there's a couple of cruise ships that are quite small, the cruise ship probably wouldn't affect us that much. Whereas a 2000 or 3000 person cruise ship would affect us," he said.
Ujazi Cafe experiences busy periods when cruise ships arrive, often setting the staff up for busy afternoons and requiring an extra person on deck to keep the coffees rolling out until they close at 5pm, Mr Quinn said.
"We are aware of when the cruise ships come and we certainly miss them when they're gone."
