Thanks to Pangakupu (aka Phi, the Indy's customary Friday setter) for doing double duty with this Prize. Relatively new to the Guardian, has done at least one Prize (iirc) and some Geniuses.
Breaking a string of three gentle Prizes, I found this tricky with longer than usual solving time. [I often lack confidence with unfamiliar setters.] Luckily got the two long acrosses quickly, which helped. More clues than usual challenging to parse: had to intuit solutions first and unravel wordplay later. A few solutions required Google to verify.
Spent some time searching for a pangram that didn't materialise. Not sure if there's a theme...there are some pairs/groups of solutions that seem related. If there's a Maori term lurking in the grid, I didn't notice it, but I'd be unlikely to find one. :-)
6d is a tricky word which I've considered but rejected as a Peer Review / Clueless candidate. Gratifying to see Pangakupu make it work!
FOI 11. LOI 24, which took inordinately long to figure out.
Quite a few outstanding clues. COD tie between 18 and 14d. Also enjoyed 20, 19, 21, 1d, 13 and 7.
