The International Rugby Board says all countries will have a fairer, more balanced programme of pool matches at the next World Cup in 2015.
Second-tier nations have been forced into a condensed schedule at previous World Cups, with countries including Samoa required to play four pool matches in just 17 days.
In comparison, top-tier teams such as New Zealand only played pool matches on the weekend, giving players a full week between games.
But IRB chief executive Brett Gosper says the schedule for the next tournament in England and Wales, which will be released in the next few weeks, will be far more equal.
