D5- Oronui hut to Mangatutara hut

Its the longest day in the southern hemisphere, however after a long day yesterday i waste half of it being unconscious till 8.30. Thankfully its not too far to the next hut.
Heading back down to the forks, i take the southern brach- Mangamatu stream. Its generally pretty easy going with a few sections walking in the water. Its name might of changed 4 times, but the almost hop-overable creek is the same catchment ive followed for 4 days since its mouth at the ocean.
At the second major forks its time to leave it behind and complete the crossing to the Mangatutara, its the first of 3 crossings required to traverse the Rakumara range. Whilst the map shows a marked route for the entire east- west crossing, theres no marking at all on the river sections and the crossings haven't been mantained in a long while. There's no evidence of a track at the start, however once out of the thick low lying scrub occasional permalot markers appear and its reasonably followable to the summit. The bush is prodominantly punga and tawa with the odd large podocarp. The summit of 800m isn't high by Rakumara standards, however its the highest point so far and the highest for a good while. 
After the summit the track deteriorates and its easier to follow a compass bearing south along the main ridge. I miss the unobvious spur heading west and somehow do a 180 looking for it. GPS and compass are invaluable.
There's a few markers untill pt 790 where they stop. 
Ive heard there's no track down the spur marked on the map, and ive tried the main spur heading west on a previous trip. Either way, by this stage all spurs drop into the same catchment, so its a case of picking one and following it. I pick the easier looking spur heading NW, and am surprised to find it contains a track. I loose the track again half way down and its time to put the compass down and bush bash downhill to the stream. The last half a k though thick scrub takes over an hour. I bump into the track again 20m before the steam.
Its a relief to finally reach the broad gravel of the Mangatutara stream, at some point I've crossed the main divide as rivers now flow west into the Motu/ Bay of Plenty. A blue shape stands out in the bush, and im surprised to see a hunter and son, fly camping in the valley, its the first white faces I've seen since the lighthouse.
The Mangatutara's an easy and pleasant walk. There's 2 short gourge sections seperated by broad gravel flats. Mangatutara hut's rumoured to still exist, and in fact it does. Its easy to miss and walk straight past, last time i was here there was thick scrub making it invisible from the stream. The scrubs been recently cut and if you stand in the right place it can be seen from the riverbed. Probably more importantly deer in the riverbed can be seen from the hut.
Mangatutara hut gets more visitors than Oronui, buts its mostly fly in hunters, with only 2 or 3 tramping parties a year. Its got 6 bunks, tank water, an open fire place, and the best stocked food cuboard I've seen. Being a day ahead of schedule, I've got more than enough food so i swap some rice for noodles.
