Consumer NZ is backing Labour's policy to shake up the legal system to make class action lawsuits easier. 

Labour says it will establish a formal class actions regime, allowing groups of people to band together to sue. 

Leader Chris Hipkins says people are blocked out of justice due to costs or system delays. 

Consumer NZ Chief Executive John Duffy told Kate Hawkesby that class action lawsuits are rare in New Zealand. 

He says they're very common overseas, and often used for consumer rights, health and safety, and environmental issues.
