Work Visa

Your new employer would organise a new visa for you.
As you circumstances have changed you cannot come back on your existing visa.

I suggest an online search for work.

Thank you.

@Stumpy,

Should it be an issue to enter with a valid stamped visa? If someone has not undergone a proper cancellation or expiry process, the stamped visa should be valid for multiple entries until it gets expired. I mean I may not have enough knowledge about it, but just a second thought.

@Mahalosun!
It's quite obvious that you could only come back based on a new employer's visa.

@schaz

As far as I am aware the problem would be that the circumstances on which his partnership work visa have changed so this invalidates that visa.

If the OP was to successfully enter on that visa and find work (for which he will need another visa type), then immigration are likely to find out the circumstances of the original partnership visa. Then they can refuse the new visa as he entered the country on the partnership visa which technically was invalid due to the changed circumstances of the partnership.

then immigration are likely to find out the circumstances of the original partnership visa

That's the point. Rightoo!!!
