Gallaway (89), who had a commentary career that spanned 40 years, will have his life celebrated by family, friends, the law fraternity and commentary peers all wanting to pay respect to the Otago icon.
Otago Cricket Association chief executive Ross Dykes said the March 9 dinner aimed to give Gallaway the "recognition of his fantastic contribution to Otago and New Zealand sport.
"Iain has given so much to sport and, like Otago cricket, he is big on tradition, so we thought it would be a nice gesture."
Bill Francis, Bryan Waddle, John McBeth, John Parker, Steve Davie and Gallaway's son, Garth, are among the broadcasting community's elite who will make the trip to honour the former voice of Carisbrook.
Otago cricket would like to host a test every year and if that happened it would be holding tribute dinners related to Otago people, Dykes said.
"There are players and administrators who have given so much to Otago sport and an annual dinner around test matches would be a nice way to recognise them."
Gallaway was born and raised in Dunedin. He played three first-class matches for Otago as a right-handed batsman and wicketkeeper from 1946 to 1948. In his first game against Wellington, he took six catches.
During his commentary career at his beloved Carisbrook, he covered 500 rugby matches and numerous cricket games.
Gallaway began commentating in 1953 and broadcast his last match at Carisbrook in 1992 when New Zealand beat India in the cricket World Cup.
During his time as a commentator, Gallaway was also an accomplished lawyer. The dinner is being sponsored by the Gallaway Cook Allan firm.
He was given a Halberg award for services to sport in 1999 and is an official patron of the Otago Cricket Association.
Dykes hopes to sell 250 tickets for the dinner. Single tickets ($140) and tables ($1400) are available.
