"I would rather someone valued it and treasured even if I never found it," she said.
Ms Chen is personally offering a $500 "no questions asked" reward for the return of the instrument.
It can be dropped off anonymously at her work at Ernst & Young, 2 Takutai Square, Britomart.
Ms Chen can be contacted on 09 377 4790 or 021 680 467 or by email on jenny.chen@nz.ey.com.
