Warranties & Guarantees

Sea Tech Ltd is the official New Zealand agent for all the brands shown on this website. For your own peace of mind that means that you are covered under New Zealand consumer laws as well as each brand's individual warranties and guarentees.

Consumer Guarantees Act 1993

The Consumer Guarantee Act sets out minimum standards for goods sold by Sea Tech. In the event that goods sold are not of good quality or are faulty, the customer has the right to a repair, replacement or a refund.

Fair Trading Act 1986

The Fair Trading Act is designed to protect the customer from being misled, either intentionally or unintentionally. This applies to all aspects of the promotion and sale of goods and services including: pricing; where the product was made; where the product is from; the meeting of New Zealand safety standards; availability of products in store and the sales techniques used.

The Commerce Commission enforces the Fair Trading Act 1986.

Our promise to you

While the Consumer Guarantee Act and Fair Trading Act provide the basis for Sea Tech, we want to go above and beyond the expectation of these two statutory laws.
