The Hawaii News Now article is short on poll particulars and doesn't include a link to crosstabs - yet. But yesterday's Gubernatorial poll should give us some insight. I doubt they ran a separate HI-01 poll.
The Gubernatorial poll was taken Oct. 11-18 by Ward Research. It was of 605 voters (unclear from HNN if registered or likely). That probably means the HI-01 subsample was of about 300 voters, giving the poll an MoE of around +/- 5.7.
