Technically, the drilling system was a success, and although it did not preform to its expected capabilities, the modifications necessary to accomplish this are feasible. The main problems and necessary modifications are listed below in order of importance:

1)	Core bits need further testing and design. With the present system, the clearing of cuttings, and in particular ice-rich cuttings, becomes more difficult with depth below about 2 m. Unless this problem is solved, holes deeper than about 10 m are not practical with this system as reaming is required below 6 m.
2)	The compressor system generally worked well, but consumes a lot of fuel and requires a dedicated operator. Modifications are required to the protective box so that the compressor and its coalescing filter can operate in a warm and uniform temperature. It may also be possible to reduce fuel consumption if demand air flow can be regulated.
3)	Cooling of the compressed air is required and drilling in temperatures above −3°C is probably not practical. In addition, moisture from compressed air must be removed before entering the cooler. With the present system it is not practical to drill in either cloudy or snowy conditions because of ice build up in the air ways.
4)	Unquestionably a drilling shelter is needed for winds greater than about 7 knots. However, the present shelter and platform can be lightened in weight and simplified in design to increase set-up and break-down time.
5)	A drilling camp of at least 5 people is required to support the present drilling system. The camp, drilling system, and fuel (five 12 hour days of compressor operation) translate into 6 helo loads (3 internal and 3 sling). The logistics of such moves are complicated and demanding on Antarctica NZ resources and suggest that one and possibly two areas can only be drilled in a season.
