Help spawning an object relative to the local Z axis of an object

So I want to spawn an object to the relative forward location to the spawner but I can only make it spawn relative to the global forward direction.

This is the global rotation of the object this is the local rotation of the object and the object spawns relative to the global z axis

So the code I am using to spawn the next object is this

 public GameObject thingToMake;
         Vector3 poz;
 
         void Start ()
         {
             poz = new Vector3(gameObject.transform.localPosition.x, gameObject.transform.localPosition.y, gameObject.transform.localPosition.z + 4f);
             Instantiate(thingToMake, poz, Quaternion.Euler(0, 0, 0));
         }

So I am using Local position but it will still spawn the object relative to the global z direction and not to the local z direction.

Thanks in advance for answers.
