We report the results from a search for z > 6.5 quasars using the Dark EnergySurvey (DES) Year 3 dataset combined with the VISTA Hemisphere Survey (VHS) andWISE All-Sky Survey. Our photometric selection method is shown to be highlyefficient in identifying clean samples of high-redshift quasars leading tospectroscopic confirmation of three new quasars - VDESJ 0244-5008 (z=6.724),VDESJ 0020-3653 (z=6.834) and VDESJ 0246-5219 (z=6.90) - which were selected asthe highest priority candidates in the survey data without any need foradditional follow-up observations. The new quasars span the full range inluminosity covered by other z>6.5 quasar samples (J AB = 20.2 to 21.3; M1450 =-25.6 to -26.6). We have obtained spectroscopic observations in the nearinfrared for VDESJ 0244-5008 and VDESJ 0020-3653 as well as our previouslyidentified quasar, VDESJ 0224-4711 at z=6.50 from Reed et al. (2017). We usethe near infrared spectra to derive virial black-hole masses from thefull-width-half-maximum of the MgII line. These black-hole masses are ~ 1 - 2 x10$^9$M$_\odot$. Combining with the bolometric luminosities of these quasars ofL$_{\rm{bol}}\simeq$ 1 - 3 x 10$^{47}$implies that the Eddington ratios arehigh - $\simeq$0.6-1.1. We consider the C\textrm{\textsc{IV}} emission lineproperties of the sample and demonstrate that our high-redshift quasars do nothave unusual C\textrm{\textsc{IV}} line properties when compared to carefullymatched low-redshift samples. Our new DES+VHS $z>6.5$ quasars now add to thegrowing census of luminous, rapidly accreting supermassive black-holes seenwell into the epoch of reionisation.
