"As a community we have been honouring our Queen by flying flags at half-mast, signing condolence books and sharing memories.
"But we have also been honouring our new King, His Majesty Charles III. On Sunday, which was proclamation day, we returned our flags to full mast as his proclamation was shared across the United Kingdom and the Commonwealth, including here in New Zealand.
"It is an incredible time to be part of history-in-the-making and to be sharing the loss of our Queen with so many millions across the world," said Mayor Walker.
Queen Elizabeth II visited Hawke's Bay on five separate trips in 1954, 1963, 1970, 1986 and 1990 — attracting enormous crowds and fanfare each time.
Tukituki MP Anna Lorck said the Queen set a great example for many people. "She gave us the very best example of service for the greater good, of optimism, dignity, grace under pressure, motherhood, and so much more," she said.
"She was a constant sea of calm as New Zealand grew its place in the world and will be sorely missed."
Cabinet has decided that New Zealand will have a one-off public holiday and state memorial service to mark the death of Queen Elizabeth II on Monday, September 26.
Prime Minister Jacinda Ardern said many New Zealanders would appreciate the opportunity to both mark her death and celebrate her life.
"The State Memorial Service will be held in the Wellington Cathedral of St Paul on the same day, Monday, September 26, and will be televised and livestreamed.
"I know many people will want the opportunity to pay their respects and the public holiday offers communities around the country the ability to come together and pay tribute at local events also."
Ardern also confirmed she will represent New Zealand, alongside the Governor-General, at the funeral of Queen Elizabeth II in London on September 19.
Condolence books are available to be signed at the Central Hawke's Bay Council building in Waipawa, Waipawa Library and The Knowledge and Learning Hub — Te Huinga Wai in Waipukurau.
