One idea could be to plan a surprise trip to Hawaii or another Polynesian island. The experience of immersing yourselves in the culture and landscape would make for a truly unique and memorable anniversary celebration. Another option could be to commission a local Polynesian artist to create a custom piece of art for him, such as a carving or painting that incorporates traditional Polynesian motifs. You could also consider getting him a book about Polynesian culture or history to showcase your thoughtfulness and appreciation for his interests.
Or you can get him a star map with the date of your anniversary.
