There is no entitlement to breaks in New Zealand. Breaks, like overtime, hours of work, and pay rates, are decided by negotiation between the employer and employee. In workplaces without a union, these negotiations proceed the way you expect when one party has money and the other needs to eat:
Employer: We don't have breaks hereThis year was the 100th anniversary of the Blackball miners' strike. That strike was to win the right to a lunch-break, and 100 years later the government triumphantly announces that they're going to reintroduce the right to a lunch-break. Which tells you a lot about union history.
