The vast majority of Hareidi Jews are Zionist. There are small groups totalling a few thousand who are Anti Zionist but live in Israel.
The Ultra Orthodox majority not only supports the state, but are represented by religious parties in the current government under Netanyahu.
Edit: Survey data shown below shows that although Hareidi Jews in Israel participate in the government, are represented by designated parties, and those parties are members of the current government under Netanyahu, the majority of those same people consider themselves either “not too” Zionist or “not at all” Zionist.
