Among the stars who will be on the red carpet include Martin Freeman, who plays Hobbit Bilbo Baggins; Richard Armitage, the Dwarf warrior Thorin Oakenshield; Cate Blanchett and Hugo Weaving, the Elf Queen Galadriel and Elf Lord Elrond; Andy Serkis as Gollum; and Elijah Wood as Hobbit Frodo Baggins.
Sir Ian McKellen - who stars as Wizard Gandalf the Grey - is unable to attend, however Gandalf will overlook the proceedings from his newly-installed position on the Embassy Theatre.
At 9.4m tall, Gandalf joins the 13 giant dwarves in the CBD and Gollum at Wellington Airport - proof that Wellington really is transforming into the Middle of Middle-earth.
Mayor Celia Wade-Brown congratulates and thanks the many businesses, organisations and people who have dedicated their time and money into putting Wellington in the middle of the Middle-earth map.
"I especially want to thank NZ Post, Wellington Airport and the creative talent at Wingnut and Weta Workshop who have created three very spectacular installations for our city."
This weekend things really start heating up with the opening of the Hobbit Artisan Market in Waitangi Park at 12 noon on Saturday.
The free and family-focused market will be the city's Shire for five days until the premiere on Wednesday 28 November.
From glass blowers to leather workers, jewellers to sculptors, 30 artists will be displaying and selling their work.
There will be prosthetic demonstrations, competitions and Hobbit-themed food. Stalls will run from 12 noon to 6pm daily. From this Sunday until Tuesday 27 November, The Lord of the Rings trilogy will screen in Waitangi Park from 6 - 9pm (one film each night).
