Nii consonant allophones (Stucky 1973)

Phoneme	word- initial	inter- vocalic	word- final	utterance- final
/p/	[p]~[b]		[pᵊ]~[pʰ]	[pʰ]
/s/	[s̪]~[t̪s̪]~[t̪]	[s̪]~[t̪]	[s̪]~[t̪s̪]
/r/	[t]~[r](?) (after another word)	[ɾ]~[r]	[r̥] (after a vowel)
/k/	[k]~[ɡ]		[kᵊ]~[kʰ]	[kʰ]
/mb/	[mb]	[mb]~[mp]	[mpᵊ]~[mpʰ]	[mpʰ]
/ndz/	[n̪d̪z]~[n̪t̪s]***		[n̪d̪z]~[n̪t̪s]~[n̪s]
/nd/	[nd]~[nt]		[ntᵊ]~[ntʰ]	[ntʰ]~[nt𐞩̥]
/ŋɡ/	[ŋk]~[ŋɡ]		[ŋkᵊ]~[ŋkʰ]	[ŋkʰ]

/ɺ/	NA	[ɺ]**	NA
/𝼄/	NA	[ʟ̝]	[𝼄]~[𝼄ᵊ]	[𝼄]

* /ɬ/ is evidently [l̪] before a consonant

** /ɺ/ is [l] before /r/; in word-final position this sequence becomes [lt𐞩̥] ~ [ltʰ].

*** /ndz/ may have a vocoid release [n̪d̪zᶦ] at the end of a syllable before a consonant.

The account of the initial allophones of /r/ is confused, and some of the other positions are not completely clear.
