My waiver will expire on the 31 December 2014. Do I need a waiver all the time I am in the USA? I plan to enter the USA on the 30 December and leave on the 16 January.

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking.

I assume you're referring to your ESTA travel authorisation - if so: Direct quote from the ESTA Q&A page:
My travel authorization is valid for travel to the United States but will expire before I depart. Do I need to apply for a new one before my trip?
No. ESTA travel authorization needs only to be valid upon arrival in the United States.
Thus you should be fine - but do remember the immigration officers have the last say and may not necessarily like the fact you're entering the day before the ESTA expires.
