1960s - However, in the early 1960s major reconstruction on the front nine was necessitated in order to provide beachfront areas for the Kahala Hilton Hotel and the Kahala Beach Apartments. Holes number 1 and 9 were relocated completely from the green, hole number 2 retained the same green but the hole played from mauka to makai instead of along the coast, and a new tee was required for number 3. At about the same time the Bishop Estate withdrew land where the 7th hole and much of the 6th hole were located for the Kai Nani subdivision, and this required a realignment of the 5th, 6th and 7th holes. The 7th hole had originally run along the beach in a Diamond Head direction but as a result of the subdivision was relocated inland.
Along with the golf course work, a new Pro Shop and a new golf cart storage building were built on the mauka side of Kahala Avenue. The First PGA Tour Hawaiian Open Golf Tournament was held in the fall of 1965. Hawaiian Opens (under various sponsorships) have been held at Waialae since 1928. Extensive work continued on the golf course between 1965 and 1970, with the conversion of all greens from bent grass to tifdwarf, and the installation of an automatic sprinkler system throughout the golf course. During this period much time was spent in finalizing lease agreements with Bishop Estate and with Sheraton Hotels who had in 1959 acquired Matson's hotel interests and two acres of Matson land where the swimming pool and tennis courts are located. Long-term lease agreements were concluded in 1970.
