I commented on this when it first came out. Add to that the change in the understanding of "luau" not being pagan.

Luaus
I read with interest your article "Let’s Have a Hawaiian Luau." (June 8, 2002) Several years ago I attended a luau in Hawaii. I felt there were strong religious and spiritistic overtones. Even if luaus today do not involve religious or spiritistic aspects, how are they different from other celebrations that have pagan origins but simply have been adopted by modern cultures to be a family fun gathering?L.

"Awake!" responds: As noted there in our footnote on page 24, while the luau may at one time have had a connection with false religious practices, the word now has simply come to refer to a Hawaiian banquet. A specific gathering to which the word "luau" is applied may or may not be appropriate for a Christian to attend. As in all aspects of life, Christians should make decisions that will leave them with a clear conscience before Jehovah God.—1 Timothy 1:5, 19;
See June 8, 2002 Awake p. 24-27 (see footnote)
"Although the luau may originally have had some connection with false religious practices, the word has simply come to refer to a Hawaiian banquet. Many Christians may therefore conscientiously feel that they can participate."
