Neodymium magnets are incredibly strong for their size, so please handle them with care.

• Keep away from children. Two or more magnets, if swallowed, can attract to each other inside the body and cause serious, potentially life-threatening injury. Seek immediate medical attention if a magnet is swallowed.
• Watch your fingers. Magnets snap together with real force and can pinch skin or damage clothing.
• Wear eye protection. The material is brittle and can chip or shatter on impact, so take care during handling and avoid letting magnets collide freely.
• Keep clear of sensitive electronics. Credit cards, pacemakers, and other magnetically sensitive devices should be kept a safe distance from the magnetic field.

We're New Zealand's specialist supplier of neodymium (rare earth) magnets, based in Auckland and trading since 2009.

• Auckland-based and NZ-owned. A genuine New Zealand trader you can deal with directly.
• 5000+ positive Trademe reviews. A track record built on honest dealing and consistent service.
• 45+ sizes in stock, from small discs to heavy-duty blocks.
• Engineer-led advice. Our team holds qualified mechatronics engineering degrees, so the guidance you get is grounded in real technical knowledge, not guesswork.
• Quality you can rely on. Many bargain-priced magnets sold online are lower grade than advertised (often N35 instead of N45 or N52) or aren't genuine neodymium at all, so the "strong magnet" you ordered underperforms. We work with long-standing suppliers we trust, and we stand behind the grade and strength of every magnet we sell.
• Help finding the right magnet. Not sure which size or grade suits your project? Tell us about your application and we'll help you find the right solution.
• Visits welcome by appointment. Bring your project in and we'll work through the options with you in person.
• Flexible ordering. Need two half-packs instead of one full pack, or want to add a half-pack to your order? Just email us and we'll sort it out.
