Copy & paste each unique value from one sheet to another - excel

Question

I may have up to 8 unique values in column D. I am looking for a code that will copy & paste each row with unique value to a new sheet.
So I may have up to 8 new sheets.
Could you help me to build the code that will do that?
This is what I have so far:
Option Explicit
Sub AddInstructorSheets()
Dim LastRow As Long, r As Long, iName As String
Dim wb As Workbook, ws As Worksheet, ts As Worksheet, nws As Worksheet
Dim i As Integer
Dim m As Integer
'set objects
Set wb = ActiveWorkbook
Set ws = ActiveSheet
Set ts = Sheets("Master")
'set last row of instructor names
LastRow = ws.Cells(ws.Rows.Count, "K").End(xlUp).Row
'add instructor sheets
On Error GoTo err
Application.ScreenUpdating = False
For r = 17 To LastRow 'assumes there is a header
iName = ws.Cells(r, 4).Value
With wb 'add new sheet
ts.Copy After:=.Sheets(.Sheets.Count) 'add template
Set nws = .Sheets(.Sheets.Count)
nws.Name = iName
Worksheets(iName).Rows("17:22").Delete
Worksheets("Master").Activate
Range(Cells(r, 2), Cells(r, 16)).Select
Selection.Copy
m = Worksheets(iName).Range("A15").End(xlDown).Row
Worksheets(iName).Cells(m + 1, 1).PasteSpecial Paste:=xlPasteValues
Application.CutCopyMode = False
End With
Next r
err:
ws.Activate
Application.ScreenUpdating = True
End Sub
The thing is that this macro is creating new sheets, which is not necessary. I only want to make following.
If you find a unique value in column D (which will have exact name as other sheet), find this sheet and paste whole row in there.

Answer 1

Sub CopyFromColumnD()
Dim key As Variant
Dim obj As Object
Dim i As Integer, lng As Long, j As Long
Dim sht As Worksheet, mainsht As Worksheet
Set obj = CreateObject("System.Collections.ArrayList")
Set mainsht = ActiveSheet
With mainsht
lng = .Range("D" & .Rows.Count).End(xlUp).Row
With .Range("D1", .Range("D" & lng))
For Each key In .Value
If Not obj.Contains(key) Then obj.Add key
Next
End With
End With
For i = 0 To obj.Count - 1
Set sht = Sheets.Add(After:=Sheets(Sheets.Count))
sht.Name = obj(i)
For j = 1 To lng
If mainsht.Cells(j, 4).Value = obj(i) Then
mainsht.Rows(j).EntireRow.Copy Destination:=Range("A1")
Exit For
End If
Next
Next
End Sub

Answer 2

Ok, I did the workaround. I have created a list of unique values in a separate sheet.
Sub copypaste()
Dim i As Integer
Dim j As Integer
LastRow = Worksheets("Master").Range("D17").End(xlDown).Row
For i = 17 To LastRow
For j = 2 To 10
Workstream = Worksheets("Database").Cells(j, 5).Value
Worksheets("Master").Activate
If Cells(i, 4) = Worksheets("Database").Cells(j, 5).Value Then
Range(Cells(i, 2), Cells(i, 16)).Select
Selection.Copy
Worksheets(Workstream).Cells(1, 1).PasteSpecial Paste:=xlPasteValues
Else
End If
Next j
Next i
End Sub
Thank you everyone for help and your time!
