UIInput showing keyboard with space for autocomplete

[Dover8]

I have an app with a search button. When the user presses it the focus is moved to an offscreen UIInput with default settings (default keyboard, standard input, no validation). When the device keyboard opens on iOS devices and Android phones there is a gap between the input box and keyboard that would represent the autocomplete area. On Android Tablets the autocomplete tab is even displayed. I have attached screenshots to this post, but I need the input box to sit ontop of the keyboard in all instances. Using Unity 4.6.5

This isn't an NGUI thing (was there even a question in that post?) The type of keyboard opened is specified on UIInput, but beyond that it's all Unity.
