If a consumer discovers an undisclosed defect in purchased goods, what is the first step they should take?

The first step a consumer should take upon discovering an undisclosed defect in purchased goods is to contact the seller. This action is crucial because it allows the seller the opportunity to address the issue, which may include repair, replacement, or refund, depending on the nature of the defect and the terms of sale. Under New Zealand Consumer Law, consumers have rights relating to faulty goods, and notifying the seller initiates the process to resolve the problem effectively.

Additionally, contacting the seller demonstrates the consumer's proactive approach in seeking a remedy. It also creates a record of the issue, which can be useful if further actions are required later, such as making a claim under the Consumer Guarantees Act. Engaging directly with the seller is the most logical and effective first step in situations involving defective goods, as it leads to potential resolution without unnecessary escalation.
