None I would think, certainly of the larger or more complex contracts - the proof is in the on time delivery; as to the maturity and true capability of the organisation.
I disagree on your viewpoint.
HNZ has a global reach now with crew change contracts in Australia partnered with PHI and the now famous SAR contract. They have contracts in Asia and until recently in Halifax also teamed with PHI. Remember, HNZ is now a brand as well as just the old HNZ.
Yes, the SAR contract in Australia has been delayed by some unforeseen circumstances but to dismiss HNZ as incapable is foolhardy. Like it or not, HNZ is providing a service that its customers seem to like at a price the customers seem to like. Oil is now set at around $50, noncompetitive operators who misjudge their competition will be the losers.
