If you want to search caches closest to Kihei before you leave, their zip code is 96753. Looks like right now the closest one is In The Center! in Kihei.
One of our favorites is the Beer, Ice-cream or Candy cache in Kaupo. You can't approach it from Hana anymore due to the road still being out from the 2006 earthquake. So you'll need to approach it from the upcountry/Kula area (which is beautiful). Make sure you have plenty of gas before leaving the Kula area b/c there are NO services past there. The scenery is amazing and well worth the drive even if you don't find the cache. There's also a Firecracker Beach cache on that part of the highway that is neat. There's ocean and vista views everywhere so if you have a nice day, consider a picnic.
You can also check our profile for some other cache ideas or go to my blog www.truealoha.com/blog that has a special Geocaching in Hawaii section.
Have fun! What a great gift!!
