If I understand correctly, you want to create w new NIC with the same SubNet and VNet as the an old NIc in the same Resource Group.

You can use the following powershell scripts :

$destinationResourceGroup = <yourRGName>
$location = <thedestinationlocation>
$oldnic = Get-AzureRmNetworkInterface -ResourceGroupName $destinationResourceGroup -Name <theOldNICName>
$subnet = $oldnic.nic.IpConfigurations.subnet
$newnic = New-AzureRmNetworkInterface -Name <newnicName> -ResourceGroupName $destinationResourceGroup -Location $location  -SubnetId $subnet.Id

If you can also associate other resources to the new NIC (One IPaddress can only associate to one NIC)

$newnic = New-AzureRmNetworkInterface -Name <newnicName> -ResourceGroupName $destinationResourceGroup -Location $location -SubnetId $subnet.Id    -PublicIpAddressId $pip.Id -NetworkSecurityGroupId $nsg.Id

Additonal: You may want to use -IpConfiguration $oldnic.IpConfigurations to copy the same Ipconfiguration, but you would came across one issue about the associated IP address.

So, If you just want to copy a NIC, you'd better not use this command. But if you can deallocate the IPaddress after getting the Ipconfigurations of the old NIC, you can use it.

Hope this helps!
