Totally ad free I can now report I have finished. I had the wrong first word in 6d which was throwing me off. Even with the right word I can't parse it. Most of the difficulty with this was my GK but I have struggled a bit with the parsing. Perhaps as they are not a frequent Prize setter I'm not used to Pangakupu but I was not anti the puzzle as a whole as I like a challenge.
FOI after a strong start was 1a. LOI 5d.
COD 14a which was a tad clunky but nice. Thanks Pangakupu.
