Former Australian opening batsman Justin Langer has called for an end to draws in Test cricket, saying a system should be put in place where a winner is decided.

Langer says he has been thinking about the issue for about a year now, with last week's tame draw between Australia and New Zealand at the WACA Ground another example of a match fizzling out.

The Test great wants draws to be abolished in all forms of cricket, including Sheffield Shield matches.

While he isn't sure of the exact system which should be put in place to decide a winner, he says boxing is an example of a sport where a winner can be decided even without a knockout blow.

"Like a boxing fight," Langer said on Thursday.

"And there'll be some controversy about that. But there's been plenty of boxing controversies over the years as well.

"They get it right most of the time. If we take the draws out, and play a bit of day-night cricket, it's all good for the game.

"A lot of people who don't watch the game go, 'how do you play for five days and not get a result?'

"They just don't get it. Usually sport is about winning or losing, it's not about drawing."
