Forgive me for being picky, but the direction from Seaside to Auckland is SE
of you, while the direction to Manila is about 298 degrees or actually a tad
north of WNW !! However, the EWE has a wide cardiod pattern and I just
modeled your EW in EZNEC and assuming an arrival angle of 10 degrees the 3
db beamwidth is 140 degrees, so signal arriving from 73 away from beampeak
will only be down about 3.2 dB according to my modelling. So it is your
proximity to the sea that is also helping you get Philippine DX.
I've made all kinds of modelling changes to EWE's and there's nothing funny
happening at least as far as EZNEC can model it.
