Other passengers have chosen segments of the world cruise to travel on.
The 228m, 47,800 ton liner set sail from Tilbury in London back on August 31 and is due to arrive back there on May 1.
During the giant voyage it will have called at 111 ports in 51 countries across six continents, and among that giant schedule are seven Kiwi stops.
It arrived at the Bay of Islands on Monday and has called at Auckland and Tauranga and is now set to introduce its passengers to the sunshine and heat of the Bay.
It then heads for Wellington at 6pm on Friday evening with later calls at Akaroa and Dunedin, before departing for the Australian leg.
There was never any doubt New Zealand, and spots like Napier, would have to be on the schedule, Viking Cruises managing director for Australia and New Zealand Michelle Black said.
"No true world cruise itinerary would be complete without visiting New Zealand, where stunning landscapes and world-class cities go hand in hand."
She said since Viking Cruises launched their first ocean ship in 2015 the demand to sail to New Zealand had gone from "strength to strength".
Thus far, the new record-seeking liner has visited the UK, Scandinavia, Canada, the USA, the Caribbean, South and Central America and a string of Pacific Island nations.
After New Zealand it will be Australia, Asia, the Middle East, the Mediterranean and back to the UK.
Unlike on February 1 in 2018, when strong wind conditions prevented the Viking Sun from entering Napier Port, Friday's forecast is for fine weather and northwesterly winds dying out, so the record is still on.
