Well, we have also razza and razza (as in race/breed and spoke/ray/stingray) and they are respectively /ˈrat.t͡sa/ and /ˈrad.d͡za/ where the difference in pronounciation is key to the meaning.
Pizza is definitely /ˈpit.t͡sa/ (and both the t and the s are voiced).
Razzo (rocket) is /ˈrad.d͡zo/, BUT razzolare is /rat.t͡soˈla.re/ .
The z, single or double, is one of the tricky ones to pronounce properly, in Italian they are usually called zeta dura and zeta dolce "hard z" and "sweet z".
