If zinc is less reactive than sodium, then why does it still react with
sodium hydroxide?

Indeed, $\ce{Zn}$ is lower than $\ce{Na}$ in activity series of metals, so
the following reaction /won't/ take place $$ \ce{Zn + 2NaOH \not →
Zn(OH)2 + 2Na} \, . $$ Remember, however, that $\ce{Zn}$ is /amphoteric/,
so it can reacts with a strong base such as $\ce{NaOH}$ as an acid forming
sodium zincate $$ \ce{Zn + 2
