The Alpha difference
Common questions
New boat trailers in NZ range from around $2,385 for a small single-axle carpet pad trailer to $8,050 for a large tandem-axle with cable disc brakes. Alpha Trailers prices include GST and all standard fittings — no hidden extras. The right price depends on your boat size, hull type, and whether you need brakes.
Yes. Alpha Trailers delivers to anywhere in New Zealand. Waikato and Auckland customers can arrange local pickup. For everyone else, we organise freight to your nearest depot or direct to your address. Delivery costs are quoted upfront with no surprises.
Every Alpha trailer comes fully hot-dip galvanised with sealed marine bearings, LED submersible lights, Trojan or Knott branded winch, galvanised jockey wheel, bow chain and D-shackles, galvanised rims, and all fittings. Multi-roller models include the full roller system. Nothing essential is sold as an extra.
Used boat trailers can look fine on the surface but hide corroded chassis rails, worn bearings, cracked rollers, and dodgy wiring. A full recondition often costs $1,500 to $3,000, putting you close to the price of a new trailer with a warranty and zero unknowns. For most buyers, new is the safer and better-value option long term.
Tell us your boat make, model, and length along with where you usually launch. We will recommend the right Alpha trailer for your hull type and conditions — carpet pad or multi-roller, single or tandem axle. Most quotes go out within one business day.
Registration and WoF can be added for $190. This covers 3-year registration and your first Warrant of Fitness, so the trailer is road-legal from day one.
Tell us your boat — make, model, length — and where you launch. We'll match the right Alpha trailer and send a delivered price within one business day.
