Airspace Structure; Human Factors; Procedure
Aircraft X was on an ILS Runway 2 to OGG they were following Aircraft Y.  The Aircraft Y was on final and instructed to keep speed up on the approach showing 170kts ground speed.  At the time the Aircraft Y was switched to the tower about 11 mile out Aircraft X was turning base with about 6 miles in trail slowing to 170kts on the ILS to runway 2 with this about of space and adequate speed adjustments there should have been enough space on final.  Shortly after switching the Aircraft Y to the tower OGG tower called for 2 departures OGG tower only needs to call rolling calls this is Class C airspace; a few moments later the Aircraft Y slows to 90 knots over the ground with this drastic 80 kt speed reduction I didn't not think that I could slow the second aircraft enough to maintain spacing so I climbed Aircraft X to 5;000 and fly present heading to resequence them on a downwind I thought I was clear of all of the MVAs at 5;000 but just to the right of the airport the MVA jumps from 2;200 to 6;000 so I might have encroached the 6;000 MVA.In the LOA HCF has with OGG tower it states that the tower must maintain the integrity of the sequence in this situation if felt like the tower slowed the Aircraft Y to an unreasonably slow speed in order to get their departures out caused the compression that made me believe that I would lose separation on final so I broke the second aircraft out.

A HCF Controller reported of a spacing problem which led to a go around. When the aircraft was turned it entered an airspace of higher altitude; resulting in an airspace deviation.
