The question is up there.

NO.

Z-Moves don't keep the effects of the base move.

Damaging Z-Moves derive their category (physical or special) and power from the original move. For example, a Gigavolt Havoc based on Nuzzle (with a power of 20) will have a power of 100 and be a physical move, while one based on Thunderbolt (with a power of 90) will have a power of 175 and be a special move. If the Pokémon knows more than one compatible move, it will be able to choose among different versions of the Z-Move with different stats, with the instance that has the highest power sparkling. Damaging Z-Moves do not inherit any other properties from the original move, so have neutral priority and do not have the additional effects of the base move.
