Hawke's Bay CAYAD manager Laurence O'Reilly said Walsh's visit to Otatara will go ahead "even if the weather is a little unkind."
The star and wife Marjorie will be presented with whalebone "matau" (hooks) created by master-carver Hugh Tareha who gave Walsh his original matau back in 1989.
"This little pendant has taken on a talismanic character for Joe," Mr O'Reilly said.
While Walsh's role with the Eagles in New Zealand is complete, and the rest of the group flies out for a break ahead of resuming the tour in Austin, Texas, in May, the guitarist's work to assist those confronted by the perils of intoxicants is just beginning.
He and his wife are staying back for a few more days to, as Walsh puts it, "pay back" for his years lost to addiction, but has already been on one particularly symbolic event on the comparative quiet in Auckland.
One was a visit to Orakei Marae on Friday when he told a gathering of Ngati Whatua: "Don't even go there when it comes to using drugs.
"You start by using drugs and end up with them using you," he said.
On his return to Auckland, Walsh will work with CAYAD Auckland leaders BFM broadcaster Richie Hardcore and Karl Bailey and young musicians. A visit is also planned to the drug and alcohol programme at Paremoremo Prison.
At Otatara tomorrow there will be a haka-powhiri by Maori students from the EIT followed by short speeches from the Mayor of Napier, Bill Dalton, and tribal chief and Ngati Kahungunu iwi chairman Ngahiwi Tomoana.
The waiata for Joe Walsh will be a ukulele version of the Eagles' hit Hotel California by children from Greenmeadows School.
After the formalities, weather permitting said Mr O'Reilly, a lunchtime concert will be held in the Otatara amphitheatre featuring EIT Ideaschool students and graduates Jacki Houkamau, Jontelle Herbert, Fraser Mackenzie, Amanda Weedon and Scarlett Eden.
Mr O'Reilly said members of the public are welcome but should be at Otatara by 11.30am. Entry is by a donation to the Waiohiki Marae building fund.
