Narrative:

I was working local control. Aircraft Y was on 5 mile final runway 2 at 100kts. Aircraft X was on 10 mile final runway 2 270kts. I assumed hcf would slow aircraft X to follow aircraft Y but aircraft X kept coming at 270 knots. I reached out for aircraft X when he was on 7 mile final and aircraft Y was on 3 mile final but received no response from aircraft X. [Tower coordinator] reached out to hcf to ship aircraft X.when aircraft X was on frequency at 5 mile final I told him to continue traffic to follow [on a] 1 1/2 mile final. I cleared aircraft X to land when he was on a 1 mile final and aircraft Y was given taxi instructions to exit runway 2. We barely achieved runway separation. If aircraft X kept going the speed he was going we may have had a near midair collision. After talking to the pilot of aircraft X; he said he was advised about the traffic but not slowed or given a speed restriction by hcf. This has been a recurring event where we have received inadequate spacing due to speed issues that should and could be resolved further out but are being handled at the last minute or left up to tower to resolve. I recommend hcf to use speed control when applicable and ensure that the aircraft are doing what they were told to ensure separation. Maybe I could have reached out to hcf sooner to ensure separation further out.

Title: OGG Controller reports of an overtake on final that if not resolved may have resulted in a NMAC. Controller described that this type of situation is a recurring event where HCF TRACON does not provide adequate spacing on final due to speed issues.
