+### ibm_db_dbi.AsyncCursor zLOAD methods
+
+**Description**
+
+`AsyncCursor` provides the same zLOAD workflow as `Cursor`, with each call wrapped in `asyncio.to_thread` so it can be awaited from async code:
+
+- `async zload_begin(load_statement, utility_id=None)`
+- `async zload_put_data(data)`
+- `async zload_end()`
+- `async zload_get_diag()`
+- `async zload_from_file(load_statement, file_path, utility_id=None, chunk_size=1024*1024)`
+
+**Example**
+
+```python
+import asyncio
+from ibm_db_dbi import AsyncConnection
+
+async def main():
+    conn = await AsyncConnection.connect(dsn, user, password)
+    cursor = await conn.cursor()
+
+    load_stmt = "LOAD DATA INDDN SYSCLIEN INTO TABLE SCHEMA.TARGET_TABLE"
+    diag = await cursor.zload_from_file(
+        load_stmt,
+        "./ibm_db_tests/data/block.cust.del",
+        utility_id="PYZLOAD001",
+        chunk_size=10_000_000,
+    )
+    print("retcode:", diag.get("retcode"))
+    print("messages:", diag.get("messages"))
+
+    await cursor.close()
+    await conn.close()
+
+asyncio.run(main())
+```
