Barry Steenkamp, 69, does not know what he will say to Pistorius, 26, who is accused of Reeva's murder, but said he feels it is necessary "for closure", reports the Mirror.
However, Reeva's 66-year-old mother June said she never wants to see Pistorius again, as she believes he can give her no answers she wants to hear.
The Steenkamps revealed that after illness forced Barry to quit working, Reeva became the family's breadwinner.
On her last conversation with her mother - the day before she was killed — Reeva said she had deposited money in their account so they could reconnect their TV service.
Reeva's parents are worried that they could now lose their three-bed home in Port Elizabeth, South Africa.
June said Reeva was "really in love with Oscar", who had dated for three months before he shot her in his bathroom.
They now plan to scatter their daughter's ashes in the sea at Bloubergstrand - in the same place as her grandfather's ashes were scattered.
June described her daughter as a lovely, generous person, who was terribly busy, and led a very exciting life. It's almost as if she knew she only had a little time in which to get everything done, June added.
Their biggest regret, June said, is that Reeva will never have a wedding day and children.
