Commission Chair Anne Tolley remembered Kawe as a "true gentlemen" who had provided "wisdom, advice and generous character" to many mayors, councillors and staff.
"His passion for Tauranga Moana and his steadfast support of the unity of people in our city will be greatly missed" she said.
"Our sincere condolences and aroha go to his whānau at this time of shock and sadness."
Council said the flagpole on Takitumu Drive will be at half-mast on Wednesday to acknowledge his passing.
"In honour and thanks for all he has done for Tauranga."
