The Bay was to come particularly close in three challenges in the protracted buildup, losing 3-5 to Auckland in 1961, drawing 3-3 with Auckland in 1963, and losing 17-21 to Taranaki in 1965.
The 1966 opportunity came by surprise, after Waikato won a challenge against Auckland four weeks earlier.
By the time, Hawke's Bay's new tenure ended, it had established Hawke's Bay as one of the greatest unions Ranfurly Shield history, which was first presented in 1904. It was the fifth longest tenure in terms of the number of defences, headed by Auckland's 25 in 1960-63 and Hawke's Bay's 24 in 1922-27, Hawke's Bay's 50 successful defence was headed only by Auckland's 60, and fullback Ian Bishop, who landed the sole successful kick in the 1966 win in Hamilton, had risen to the top of the list of points scorers.
While some were relieved that the shield had moved on, such was the impact across many sectors of the Hawke's Bay culture and economy it was soon a dream to win it again, a wait which lasted 43 years.
After beating Otago 20-19 in Dunedin, it was only six days before it was lost to Counties Manukau, from it was regained in 2014, starting a year-long reign before it was lost to Waikato.
The Bay is scheduled to challenge Waikato on October 8.
