It depends on where you are located, not just how distant you are from 
Chili but also the angle.  They are forecasting a cone-shaped zone of 
effect heading directly towards Hawaii.  See:

CNN reported a few minutes ago that the tsunami hit New Zealand about 1 
hour ago.  Hawaii is ~3 hours more distant (as the wave travels) from 
the location of the earthquake in Chili than New Zealand, so the 
expectation is that the wave will hit Hawaii a little later than first 
forecast.

ObNANOG:  Does anyone know if transoceanic cable landing facilities are 
sited and built to resist damage a tsunami of a particular 
height/strength?  (Thinking back to the video of the tsunami in the 
Indian Ocean on December 26, 2004.)
