National are criticising Minister Michael Wood over his failure to declare his Auckland Airport shares.

The Prime Minister has stood him down as Transport Minister while he sorts out issues around the conflict of interest.

In the House, it was revealed Wood met airport executives on at least eight occasions.

National's Auckland spokesperson Paul Goldsmith says Michael Wood is in an 'untenable' position that violates the rules surrounding conflicts of interest.

"If you've got a Minister of Transport who makes regulatory decisions and legislative decisions to have an impact on the value of companies such as Auckland Airport, to hold shares in that company creates a real perception of a conflict."
