Kayaking Whakatane river

Hi I was wanting some info on the section of Whakatane river from Ngahirama hut down to Ruatoki road.
Assume it is grade 1-2 maybe some grade 3? Was planning a inflatable kayak fishing trip for 3-4 days dropping in at the hut with a chopper and floating down.
Any tricky bits? If someone has done this trip any info would be appreciated.
