I was going through my paperwork this morning, and found a letter from NZIS acknowledging receipt of my ITA. The letter had been sent out within days of my ITA arriving at the London branch. Not to worry you, but I would definitely make a phone call. When you get reception, make it clear to them that you are not trying to check the status of your application--for which they will just give you the standard 'your application may take up to ...'--but that your application was sent and receipt was never acknowledged.

You might also want to check with your bank/credit card to see if you were charged your application fee. That would indicate whether the ITA made its way into the pipeline.

Keep us posted and good luck!
