Former Australian opening batsman Justin Langer has called for an end to draws in Test cricket, saying a points system like that used in boxing could be put in place to decide a winner.

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

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