Mostly niu and ariki are glyphs which unites the hahe sign (if such it is) with the rest of the glyph. But there are a few cases where hahe is drawn as a separate unit.

Only P has niu glyphs with a separate hahe sign:

167
Pa11-20 (586) Pb4-55 (754)

It should be noted that side a of P has 599 glyphs (which we possibly now should read as 99 + 500 - if we follow our experience from E). The distance from the 'puo' type of niu to the henua type of niu is significantly 168.

Hahe joined to ariki glyphs exist in a few more cases:

Ba8-12
Oa5-405 Oa7-307
Pa7-38 Pa9-35 Pa9-41
