They're very explicit.

For example:
Fitting of or modification to: LVV Certification is not required provided that: (refer to LVV Certifier if beyond threshold below):
Body kits and components (including utility canopies, plastic bumper skins and bonnet projections)
▪ the fitting system does not weaken the vehicle structure (Note 1); and
▪ no frontal impact components have been removed where the vehicle is required to comply with a frontal impact occupant protection standard (Note 3); and
▪ the kit or components do not present any forward-facing external projections that could cause injury, to the occupants or pedestrians, or present a snagging/hooking risk to a vehicle or person; and
▪ the driver’s vision has not been affected; and
▪ the performance of any lamp is not affected as a result of the kit or components.

Basically, they're strict on safety, and lax (or don't care at all) about emissions or power.
A vehicle needs no certification as long as it meets those standards. A one-time certification is needed if you exceed them, where a mechanic inspects it. I can, for instance, do lightweight 2 piece brake rotors without certification, but if I change the calipers for aftermarket, I need them certified - but if they're meant for the vehicle, they'll almost certainly pass.
