Cannot hide navbar with ionic 2

I cannot hide navbar with ionic 2, there are couple of screens on my app need to hide the NavBar with either tabs or menu.

Hey there! Could you share what you’ve tried?

I have tried to use the tabs template to land on the first page page of the tabs and then use navPush to a new Page without a NavBar but there is still an empty white NavBar at the top, some pages don’t need the NavBar such as pages that need to use the full screen shouldn’t have the NavBar.

Please see my steps to reproduce this:
