In Google News there is a very early report from February 8, 1963, stating that Laver had lost 19 of 21 matches against Rosewall and Hoad. Since Laver played Rosewall 13 times, the remaining 8 can be inferred to be Hoad/Laver matches:

On May 16 the New York Times reported that Hoad beat Laver 8-0:
The left-hander had made his pro debut Down Under. Lew Hoad knocked him off eight straight. Rosewall won 11 of 13. But during the months in between, the education of Rod Laver has made considerable progress. In the preliminary round-robin among the full pro troupe Rosewall compiled a 31-10 won-lost record while Laver, winning nine of his last 11 matches, finished with 25-16. They will meet at the Garden tonight in another match of their 21-match playoff series for the $35,000 top prize.
And then again on September 14, the Times:
The palace revolution in pro tennis will enter a decisive phase tomorrow in the final round of the $10,000 French international championships. Who is the second-best tennis player in the world? Is it Rod Laver, the 26-year-old pro rookie? Or is it Ken Rosewall, 29, the reigning king of the game?
Today, Laver – leaping, smashing, always on the move – cut down Frank Sedgman, 6-4, 6-3, 6-2. Rosewall, as brisk and economic as always, demolished Lew Hoad, 10-8, 6-2, 6-3.
Tomorrow, Laver and Rosewall will meet in the final. There is no question about Laver’s progress since he turned pro at the start of the year. He is at least the second-best player. Is he perhaps first best?
In January, Laver toured Australia and New Zealand with Rosewall and Hoad. He played one or the other nearly every night. Hoad beat him eight straight times. Rosewall beat him 13 of 15 matches.
Laver had turned pro for a guaranteed $110,000 over a three-year period. The January tour was designed to show fans Down Under in the most graphic way possible the difference between amateur and pro tennis.
Through the Tennis Mill
Also it was meant to put Laver through the mill, to make him into a top pro quickly, or break him. “We believe that all that hard traveling brings out character in a man,” said Tony Trabert, the director of the pro tennis tour.
“A top player must learn to play on grass one night, boards the next. He must learn to play when stiff from traveling all day, when he isn’t eating properly, when he hasn’t slept well.”
The January tour drew an average of 9,000 fans a match. It also made Laver into a pro overnight.
By the end of the spring, Laver was able to beat Hoad most times. In tournaments this summer, he managed to beat Rosewall, too. He won three tournaments – in Cannes, France; Kitzbuhel, Austria and Noordwijk, Holland. Andres Gimeno of Spain won the fourth tournament in Portschach, Austria.
