An unusual visitor coming to Auckland is the Italian RO/RO vessel Grande Cotonou IMO 9672105 owned by Grimaldi Lines. She is doing Jeddah - Melbourne - Auckland - Shanghai.
This must be a new scheduled service, as a second vessel Grande Florida IMO 9782716 is also listed on the same port rotation. The first vessel is due Auckland 21 May and the second 11 June.
This appears to be a "Round the World Service". The Grande Florida is now due Auckland 11 July, in from Port Kembla and out to Nagoya.
The next two vessels are Grande Napoli IMO 9247924 due from Antwerpen 14 July and out to Nagoya, and Grande Baltimora IMO 9784037 due 31 July from Melbourne and out to Busan.
Some vessels are coming down via Suez and others via Panama, but I can't locate a shipping schedule online.
