Which iPhone part has actually failed
Most wasted part orders come from diagnosing by symptom rather than by cause. The pattern below covers the faults that walk into the workshop most often.
Cracked glass, display works. Screen assembly. If the glass over the rear camera is the cracked part instead, that is a lens cover, which is a far cheaper item.
Battery dies by lunchtime, or the phone shuts down in the cold. Battery, and it needs fresh battery adhesive to refit.
Charges only at a certain angle, or not at all with a known good cable. Charging port, though clean the port with a dry brush first because lint is a common false alarm.
Screen stays dark on calls, or auto-brightness stops working. Earpiece and ambient sensor assembly rather than the display.
Photos hazy or unfocused. Camera module. Cracked outer glass with normal photos is the lens cover only.
Parts by component
Everything is filed by component rather than by generation, so restocking a shelf means one category rather than a search per model. Screens, batteries, charging ports, front and rear cameras, camera lenses, home and power and volume buttons, earpiece and ambient sensors, NFC antennas, screws and the full adhesive range are all stocked separately.
Adhesive is not optional
Original adhesive does not reseal once it has been lifted, so a screen or battery replacement without fresh adhesive leaves an edge that lifts and lets dust and moisture in. Screen adhesive, battery adhesive and back cover adhesive are stocked as separate items for each model, and they are the part most often forgotten from an order.
Sourcing iPhone parts in New Zealand
GA Tech NZ has supplied the New Zealand repair trade since 2017 and fits these parts on its own bench, so the range reflects what survives real use rather than what is cheapest to import. Stock is held in Queenstown rather than ordered in per sale, so orders placed before the 2pm cut-off dispatch the same working day and reach most New Zealand addresses overnight. Local pickup is available by appointment, and repair shops and resellers can request trade pricing through wholesale deals.
The tools for the job are under repair tools. If you would rather not attempt it, request a repair or a fault assessment.
iPhone parts questions answered
Do I need new adhesive when replacing a screen or battery?
Yes. The original adhesive will not reseal once lifted. Screen adhesive and battery adhesive are stocked separately for each model and should go in the same order.
How do I find my exact iPhone model?
Open Settings, then General, then About, and read the Model Name. Match that name rather than the release year, because parts differ between models of the same size.
Will the phone show a warning after a non-Apple part is fitted?
iOS can display a parts notice after a screen or battery replacement. The phone works normally, and each listing notes what to expect for that part.
Do you sell to the public or only to repair shops?
Both. Anyone can order at listed prices, and repair shops and resellers can apply for trade pricing through wholesale deals.
