The England coach is among a number of leading coaches, officials and players attending a three-day International Rugby Board (IRB) conference in Auckland on the state of rugby.
Woodward coached England to a thrilling extra-time victory over Australia in the final of the World Cup in November. The tournament hosted by Australia brought together the world's top teams and referees, raising several issues including the differing interpretations of some laws such as the use of decoy runners and the tackled ball situation.
Questions were also asked over the liberal use of substitutes. But Woodward, who was knighted in Britain's New Year honours following the World Cup victory, said the laws themselves needed no changes.
"I think the laws are fine," he told journalists before the start of the final day of the conference. "From what I see so far, I don't think the laws need changing at all. It's just the way it's coached and refereed."
Woodward was due to give a presentation to the conference Thursday on decoy runners. During last year's World Cup, he complained about the tactic, which can amount to obstruction in extreme cases, saying he wanted its legality clarified.
On Thursday he said there was a need for everyone to work from "the same mindset". "The law on decoy runners is fine, it's the interpretation of it," he said.
The same applied to the law on the tackled ball, with many players and coaches not fully understanding what was permitted. He added he could understand why some people would want to change the substitution rule, which often sees teams clear their seven-strong bench of substitutes late in the game as starting players tire.
But the danger was in overreacting and, "You can sometimes tinker too much," he said.
Officials attending the conference also include new All Blacks coach Graham Henry, Australian coach Eddie Jones, France's Bernard Laporte and Ireland's Eddie O'Sullivan.
Geoff Evans, the IRB head of development, described the conference as a discussion forum with no decisions being taken. Recommendations will however be taken forward to the board's annual meeting in April.
