Putting the 'h' back in Wanganui (fwd link)

[William J Poser]

For those with no knowledge of Maori, the difference between <wh> and <w>
in "Wanganui" versus "Whanganui" is not a mere matter of spelling
as the Mayor seems to think. <w> represents the same sound as in English,
while <wh> represents a voiceless bilabial fricative, similar to English
/f/ but made with both lips rather than the lower lip and upper teeth.
