I believe the answer is:

ulterior motives

I'm a little stuck... Click here to teach me more about this clue!

'dubious reasons?' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'new ute? morris love it' is the wordplay.
'new' indicates an anagram.
'ute'+'morris'+'love'+'it'='utemorrisloveit'
'utemorrisloveit' with letters rearranged gives 'ULTERIOR MOTIVES'.

'for' is the link.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
